The invention relates to optics and, more specifically, to the design of lenses for sunglasses, decorative, advertising or club holographic glasses, the effect of which is provided a holographic image arising from the illumination lenses natural or artificial light. It is intended to reduce the color contrast aperture lenses in transmitted light by increasing the brightness of the holographic image, and to improve their retention brightness of this image and improve the impact properties of the lenses, it is important to protect the user's eyes in case of accidental damage to the lens.

Recently, holographic glasses are used to protect the eyes from bright sunlight or artificial light, as well as in advertising and decorative purposes, bringing to the attention of the surrounding people and their lenses light radiation is used to form the holographic image. It is a percentage, defined diffraction efficiency of the hologram, can be 50...70% [1].

Holographic glasses used for decorative or advertising purposes, to increase the brightness and expressiveness of holographic images using holograms of objects with inhomogeneous spatial properties, which leads to spatial variations in diffraction efficiency of the holograms on the aperture of the lens. This, in turn, leads to a spatial modulation of light passing through them, which is expressed in the formation of color patches, causing discomfort to the user and cause fatigue and eyestrain. The color contrast between the spots is the larger, more expressive, rich detail and shading is recorded in the hologram of the object, and accordingly the greater the difference between the local values of the diffraction efficiency of the hologram of the object. Artificial reduction of the diffraction efficiency of the hologram reduces the specified color contrast, but at the same time decreases the brightness and expressiveness of the holographic image. These points become less attractive and the efficiency of their application nevasurrenda great brightness and expressiveness of the formed image and high spatial uniformity of the light passing through them flow, characterized by low color contrast aperture lenses. This is due to the inconsistency of such requirements for a well-known designs of lenses, in which the layer of the hologram, in addition to imaging, has the function of attenuating the intensity of the transmitted radiation.

It should be noted that a number of known types of holographic glasses (e.g., sunglasses) lens design also contains a layer with a hologram and a special protective layer. The protective layer reflects or absorbs some of the radiation and, therefore, provides additional protection to the eyes from the bright rays. But it is not possible to solve the above problem, because it has a uniform spatial and spectral optical properties.

Known lens hologram glasses [1], designed to protect the drivers from glare containing deposited on a transparent substrate layer with a volume reflection hologram mirror having a high diffraction efficiency in the desired narrow range of angles.

However, the specificity of the entry object (flat mirror) significantly limits the scope of possible application of such lenses.

goals contains transparent base, which is applied to a partially reflective and partially light transmissive layer, including the surface (relief) hologram, working on the transmission. The entry object is flat or three-dimensional reflective subject. The attenuation of radiation is carried out using a semi-transparent metallic coating. However, the metallic coating does not compensate for the spatial heterogeneity of the transmission layer with hologram, because it has a uniform spatial and spectral optical properties.

Known holographic lens sunglass [3], containing eyepieces coated with thick emulsion in which recorded (in colliding beams) volume reflection hologram of the scattering object. The transmittance of the emulsion is adjusted by selection of the exposure time and mode of manifestation. Protection from intense radiation in the lens [3] in fact is due to reflection from local centers of reflection and absorption, formed in the emulsion during recording of the hologram, and by increasing the optical density (loss of transparency) of the material formed by fotokem the s layer with hologram in addition to its main function of forming images, and also more easing functions transmitted radiation over the entire spectral interval. This does not, as in [2], to reduce the spatial modulation of the radiation, causing discomfort to the user. In addition, this layer weakens and on the hologram diffracting the radiation forming the holographic image, due to the absorption of as centers of reflection, and the material layer. As a result, the brightness of the image is reduced, it is relatively dim, blurred, and therefore it loses its expressiveness.

Closest to the claimed lenses are for decorative sunglasses [4] containing optically transparent base, is used as the substrate on the internal surface of which, facing the user, caused partially reflective, partially transmissive layer of the holographic emulsion, which is recorded at least one hologram. The hologram can be made on flexible media (film) or may be superficial (made by stamping hard on the media, as in [2]. Lenses are in the latter case, a partially transparent protective element, osushestvlyaetsya in the specified emulsion (also, as in [3]). While the protective element may be a coating of lacquer type or precipitated abrasion-resistant layer, or glass.

As a prototype we have chosen the option of recording a volume reflection hologram in a partially reflective, partially transmissive layer. This layer provides the basic attenuation of the light flux due to reflection from local centers of reflection and absorption, formed in the emulsion during recording of the hologram, and due to the partial transparency of the emulsion material. Additional light attenuation in the protective element provides the support possible to change the transmittance of the lenses [4] within the required limits. However, this solution is private, i.e. not required in all cases of application points [4], since the protective element is not mentioned in the claims. The recording of the hologram is produced in colliding beams, or when the reference beam incident on the emulsion layer at an angle of 20-40oand the subject is directed from the back side layer after reflection from the recorded object. Hologram produces an image that can be localized either in the plane of the substrate, either by the user or is the function of protection from intense radiation performs a single layer layer with hologram. So what is the use for this layer completely, not partially transparent material is not allowed in principle. This layer weakens passing radiation across the visible range of the spectrum including spectral interval in which the maximum diffraction efficiency of the hologram, reducing at the same time and the brightness of the radiation forming the holographic image. Therefore, the prototype in full has all the disadvantages described above in the analysis of similar [3]. Does not change the situation and the use of a protective layer, not with spectral selectivity (at least about this in [4] is not mentioned) and evenly over the range of attenuation passing through the layer of radiation. As the layer with the hologram, a protective layer does not reduce the color contrast on the aperture of the lens, resulting in transmitted radiation due to the spatial modulation of the radiation caused by the formation of a holographic image and, therefore, does not reduce the discomfort of the user.

In addition, in [4] does not include provisions for the protection of the user's eyes in case of accidental damage to the lens, and the possibility of the relevant properties to the material of the protective layer is not described is isenia color contrast aperture lenses in transmitted light by increasing the brightness of the holographic image. Additional objectives are to increase their retention brightness of this image and improve the impact properties of the lens to enhance the security of the user's eyes in case of damage to the lenses.

This is accomplished by the fact that in the holographic lenses for glasses containing optically transparent base, one surface of which is a layer that contains at least one volume hologram according to the invention the said layer is made of a material transparent in the spectral interval in which the maximum diffraction efficiency of the hologram, and the layer with hologram by the user is additionally at least one compensation layer, made of a selectively absorbing material with a maximum spectral transmittance outside the specified spectral interval and is used to reduce the color contrast aperture lenses in transmitted light by increasing the brightness of the holographic image generated by the illumination lens.

The invention is based on the properties of volume holograms recorded in a fairly narrow spectral range with the centers form a volume diffractive structure in this layer and differ in their optical properties from the material layer. When covering layer with hologram broadband radiation from natural or artificial origin of its maximum diffraction efficiency is manifested in the corresponding is also quite narrow spectral interval. Therefore, the spatial modulation of the last layer of the radiation is maximum in this spectral interval, whereas the radiation of other wavelengths is practically not modulated.

Hence it becomes clear idea of the present invention, based on the relative weakening of those spectral components of the last layer of radiation that are within the specified spectral range, corresponding to the maximum diffraction efficiency of the hologram, i.e. those components that are responsible for the emergence of spatial modulation of the radiation perceived by the eye of the user in the form of color patches. This allows you to reduce the color contrast between the spots on the aperture of the lens and thereby to solve the problem.

Note that to implement this idea is not applicable, the established practice of attenuation of radiation by the layer with hologram unrelated to the spectral interval in which the poppy is the brightness of the holographic image. As already mentioned, this is due to the inconsistency in this case, the requirement to reduce the spatial modulation of the transmitted radiation and increase the brightness of the holographic image. Therefore could not be solved in principle and task.

Implementation of the idea of the invention is carried out by the authors ' proposal with added compensation layer made of a selectively absorbing material and having a maximum spectral transmittance outside the specified spectral range, and the minimum - for example, within this interval.

The fact that the weakening of the radiation compensation layer is performed by absorption rather than reflection, creates the best conditions for observing the holographic image, by excluding radiation of the same color from the surrounding background image. When this form of the compensation layer can be very diverse. For example, it can be executed in the form of a plate made of a material that absorbs radiation in the specified spectral range, and the aforementioned layer with hologram inflicted on him as a substrate. In another embodiment, it can be made of what intervale and deposited on the layer of the hologram. On the compensation layer can be assigned protection from bright light, if it is made of partially absorbing material in the rest of the visible range outside the specified spectral range. In these or other embodiments of the compensation layer has a nonuniform absorption spectrum with a maximum spectral transmittance outside the specified spectral range. Selection of material compensation layer according to the above optical properties can be carried out according to the published tables and atlases absorption spectra.

In addition to the immediate implementation of the inventive concept, the introduction of a compensation layer and provides independent optimization of the optical properties of the layer with hologram, which thereby can be made of a material transparent in the specified spectral range. As in this case, the radiation, forming a holographic image that is not absorbed by the material layer with a hologram (in contrast to [3,4]), it is possible to get the maximum possible under other equal conditions, the brightness of the image. Moreover, the holographic image becomes more clear (because of better reproduction is their surrounding to the user points.

Additional opportunities to increase the brightness of the holographic image occur when not only the material used for recording volume holograms, but also local centres created in the recording of the hologram and forming therein volumetric diffraction structure, which does not absorb radiation in the specified spectral range. These centers are, for example, local changes in the refractive index generated in the layer ukrainophones gelatin. Natural or artificial radiation, diffracted them and scattered them back, forms a holographic image, which is seen by the observer in the aperture of the lenses of the user. These optical properties (no absorption) these centers differ from the centers of reflection and absorption, forming a structure of the reflective holograms recorded in the materials of the type of photographic emulsion used in [3, 4]. Therefore, dimensional holograms formed by these centers without radiation absorption and called us "rasseivatelei", differ from those reflective holograms, and their use provides an additional increase in the brightness of the image.

Thus, introduced the, but desirable type hologram (rasseivatelei hologram) to optimize the brightness characteristics of the holographic image.

If you need additional increase the brightness of the image and eliminate glare, it is advisable that the base had on my external to the user surface ar coating (for the specified spectral range, in particular) to reduce the radiation loss at the interface of the base of the atmosphere.

Ar coating can be applied and converted to the user surface of the compensation layer (or the last of such layers, if more than one) or a substrate of optically transparent material, for example, in the form of a plate. In all cases, the coating is applied to the surface of the extreme element of the design of the lens, which is therefore simultaneously a corresponding surface of the lens facing the user. When using holographic glasses as decorative indoors (club, for example, with a number of spaced light sources such coating eliminates glare radiation of these sources from the inner surface of the lens and to prevent the formation of nuisance p. the radiation.

The use of compensatory layer gives another opportunity to enhance luminance contrast holographic image (especially monochrome) sold due to selection of the color of the background. For this render holographic image advisable to compensation layer had on one of their surfaces partially reflective coating to reflect light of a desired color shade. For example, if the maximum diffraction efficiency of the hologram falls on the spectral interval in the green part of the visible range, the most preferred is a shade of yellow.

Of course, all of the above concerning the nature of the present invention also relates to the use cases in the lenses of two or more holograms. However, recording multiple holograms provides additional features depending on the destination points. So, if all these holograms have the maximum diffraction efficiency in the same spectral interval, they can be recorded at different angles of incidence of the reference beam lying in successive angular intervals, covering specified plavanie opportunities offered lenses as a means of demonstrating the observer changes in the same holographic image in the dynamics involving attention. Although in this case it is enough to have one compensation layer, however, can be applied and a larger number of such layers, for example, to minimize color contrast aperture lenses. It is clear that the angular range, and the order of the entries (which holograms can be different depending on the desired decorative or advertising effect.

To obtain multi-color holographic image of the object recording holograms individual object fragments may be produced in the same angular range (for example, in colliding beams), but in different spectral intervals. Thus for technological reasons, it may be preferable to use not one but two or more of the compensation layers to reduce the color contrast aperture lenses in the respective spectral intervals.

The analysis of the nature of the invention and the various options for its implementation proves the validity of the choice of total essential features describing the inventive glasses for holographic points, and n is patentosposobnaya of novelty.

The analysis of the prior art follows that the task was set by the authors for the first time, and it turned out to be unconventional and even contrary to established practice in this field of technology. This allows us to conclude that the claimed invention meets the condition of patentability on inventive step. Confirmation of this can be, for example, that this distinctive feature, as mentioned compensation layer with specified optical properties and purpose, was not detected in well-known authors analogues in the field of technology related to holographic glasses.

The invention admits wide variation of properties and forms of implementation of the various elements of the design of the lenses or combinations thereof, and retains the ability to solve the problem, providing an opportunity for selecting the optimal technological and constructive solutions.

Optically transparent base may be made of polymeric material used in the creation of normal lenses megalograptus points, or silicate glass. However, for the convenience of users who reject the view from the norm, the basis may have the emer, the form of a flat plate, and the shape of the lenses for vision correction has the backing of the compensation layer, located on the user side and is made of optically transparent material. This preferred option is to perform a compensation layer of optical adhesive, which is applied on the substrate and contains an additional substance, absorbing radiation in the specified spectral range. Optical adhesive binds the lens for vision correction and layer with hologram, applied on the substrate to face the user, the inner surface of the base, in a single structure, which has several advantages. Layer hologram is it isolated from the environment, which significantly reduces the rate of degradation of the properties of this layer and can increase the retention of brightness and expressiveness of the holographic image. On the other hand, in mechanical terms, this design is similar in design to type "triplex": in case of damage, for example, because of a sharp blow, the lenses are not broken into separate pieces, and the only crack that increases the security of the user's eyes.

Thus, the claimed invention allows to solve these topoi can be made in the form of a plate of material, absorbing radiation in the specified spectral range to which the substrate is coated with the layer hologram, and the base is made of a plate of transparent material and is connected to the layer with hologram layer of the conventional optical glue. If necessary, the layer with hologram can be sealed between the base and the compensating layer with a layer of sealant bonding material such as glue applied on the end surface of the lens. The arrangement layer with hologram and its material (for example, it is photopolymer), and the form of implementation of the compensation layer can be arbitrary.

The invention allows for the assignment of the individual elements of the design lens additional features. On the compensation layer may be imposed, as mentioned above, protection from bright light. Another solution that may be applied to the compensating coating layer, partially reflecting the radiation from the rest of the visible range outside the specified spectral range.

Described and other embodiments of the invention are shown for illustration in Fig.1-8, there is shown a cross-sectional design of the lenses. In Fig. 9 shows a view frame layer. In the illustrations of Fig.1-8 the following notation is used: 1 - base; 2 - layer hologram; 3 - compensation layer; 4 - base compensation layer; 5 - layer optical glue; 6 - ar coating; 7 - sealing layer; 8 is a partially reflective coating. In these figures, the layer 2 with a hologram applied on the substrate on the basis of 1 (Fig.1-4, 6, 7) or on the compensation layer 3 (Fig.5, 8). Thus, the base 1 has the shape of a flat (Fig.1-3, 5, 6, 8) or curved (Fig.7) plate and provided with antireflection coating 6 (Fig.5), or has the form of lenses for vision correction (Fig.4). The compensation layer 3 made of an optical adhesive, which additionally contains a substance that absorbs radiation in the specified spectral range (Fig.1, 2), or has the shape of a flat (Fig.3-6, 8) or curved (Fig.7) plate made of a material that absorbs radiation in the specified spectral range. While on one surface of the compensation layer has a partially reflective coating 8 to render the holographic image (Fig.6) or ar coating 6 (Fig.8). For the formation of unified design elements of the lens are connected using an optical adhesive 5 (Fig.3-6, 8) or the sealing layer 7 (Fig. 7). In Fig.1,2 this function performs to the .1) or lenses for the correction of vision (Fig.2).

Because if you implement all these options are well-known items, materials and substances, the production of which is mastered by the industry, and methods of coating layers on different substrates, the introduction of these substances, as well as recording of holograms are well known experts in their respective fields of engineering and technology, it can be considered that the claimed invention meets the patentability requirements of industrial applicability.

For a better understanding of the essence of this invention, the following is the mathematical modeling results for variants of its specific implementation is shown in Fig.3.

In the simulation it was assumed that the holographic lens for glasses contain optically transparent base 1 of the silicate glass, having the form of a plate (thickness 1.3 mm), on the internal surface of which, facing the user, deposited on the substrate layer 2 photoresistive material - ukrainophones gelatin (thickness 0.01 mm), which recorded one volume rasseivatelja hologram. For the spectral transmittance of the layer 2 with the hologram was made of the experimental values obtained in areas of lcno transparent. The maximum diffraction efficiency of the hologram was achieved in the spectral interval of width 20 nm centered at this wavelength. On the layer 2 by the user is the compensation layer 3 made in the form of a flat plate and providing increased absorption of radiation in this spectral interval in the green region of the spectrum and the maximum transmission out of it. The dependence of the spectral transmittance of the compensation layer 3 from the wavelength as follows, respectively:
Wavelength, nm: < 520; 530; 540; 550; 560; 570; 580; > 590;
Transmittance, %: 100; 76,1; 10,9; 16,3; 21,7; 50,0; 86,9; 100.

According to the results of mathematical modeling, we determined the coefficient of light transmission of the lens, the color coordinates of the past through the lens of radiation daylight (standard source D65) and the changes of these quantities for areas lenses with maximum and minimum diffraction efficiency (which was assumed to be equal, respectively, 70% and 0.1%). These results were obtained as for the case of using the compensation layer 3 in the design of holographic lenses, and without it.

In the absence of a compensation layer obtained the following values of wage transmittance of the lens k = 72,4%;
- color coordinate of x = 0,340, the color coordinate y = 0,358; for areas with maximum diffraction efficiency
- the ratio of the luminous transmittance of the lens k = 62,3%;
- color coordinate of x = 0,340, the color coordinate y = 0,335.

Change the color coordinate y value is 0.023 within the aperture of the lens is quite significant. This spatial modulation of the spectrum passing through the lens radiation is perceived by the user points in the form of clear-cut violet-purple spots (places where the diffraction efficiency is maximum) on a light gray background (where the diffraction efficiency is low). For greater clarity in Fig.9 (left) illustrates the kind of aperture holographic lenses by the user, which is clearly seen in this case the interference is in the form of spots of color in the form of a recorded image (outline of a bat).

When using the compensation layer in the structure of the lens obtained the following values of the above quantities:
for areas with minimum diffraction efficiency
- the ratio of the luminous transmittance of the lens k = 49,4%;
- color coordinate of x = 0,342, the color coordinate y = 0,296; for areas with Maca coordinate x = 0,342, color coordinate y = 0,295. As you can see, the spatial variations of the color y coordinates are in this case only 0,006 within the aperture of the lens. Such modulation is no longer perceived by the eye, moreover, that due to the selective nature of the radiation absorption compensation layer is the background color of the aperture is shifted in the direction of Magenta color, which disguise its small changes (see Fig.9 right).

Thus, the use of compensatory layer with the specified properties has greatly reduce, and in some cases completely suppress spatial modulation through the lens of radiation caused by the formation of a holographic image. This gave the opportunity to increase the brightness of the image by increasing the diffraction efficiency of the hologram recording it in the recording material in the form rasseivatelei patterns, less debilitating diffracted her radiation, and the use of such a recording material after the recording of holograms in it has the greatest transparency. As shown above, such opportunities do not have any analogues or prototype of the proposed the x points having a diffraction efficiency of 50%, when the ratio of the light transmittance of 40% and the no observed eye spatial modulation of the radiation in the form of color patches. Such characteristics, in principle unattainable for the prototype.

Glued the lenses are cut and obtochuyut form of fenestration of the eyeglass frame (fasterova) and inserted into a suitable frame. The lens is then ready for use.

The inventive lens for holographic points are as follows. Natural or artificial radiation falls on the base 1 and, passing through it and the layer 2 with rasseivatelei hologram, dirigeret without absorption on distributed in the volume of this layer receiveing centers (local change of the refractive index). Diffuse ago these centers radiation forms a bright holographic image (e.g., bat) in a narrow spectral interval the green part of the visible range, which is seen by the observer in the aperture of both lenses. Since layer 2 emissions of the specified spectral range to the greatest extent absorbed by the compensation layer 3. Radiation outside the spectral interval in the rest of the visible on ovcu in purple-brown tones without interference in the form of color patches, due to the spatial modulation of the radiation that would be visible in the absence of the compensation layer 3.

Examples and various embodiments of the invention are not exhaustive. So, a possible implementation in which the warp performs additional functions that can simplify the design points. For example, if the base is made clear in the rest of the visible range outside the specified spectral interval and contains the substance absorbing the radiation in this spectral range, it is at the same time and the compensation layer, and the layer with hologram printed on the external to the user surface of the base as the substrate. To improve the adaptation of the user to the harsh conditions and frequent changes of illumination, for example, the transition from light to shadow, can be a useful option, in which the wear layer is separated from the layer with hologram added layer made of a photochromic material that changes optical transmission across the aperture of the lens depending on the intensity of the light.
