Radiation dissipating device

FIELD: radiation shielding and masking systems, those producing illumination effects (advertisement, decorative lights), data display systems.

SUBSTANCE: proposed device that can be used for dissipating electromagnetic radiation, such as light, radio waves, X-rays, as well as for dissipating particle streams is, essentially, multilayer screen some of whose layers are deformable ones. Electric field is built up between two electricity conducting layers due to voltage applied to these layers. In the process conducting layers are split into segments and separate electrodes are brought to respective layers. Voltage applied to separate segments permanently varies with the result that electric field produced is nonuniform and deformable layers are embossed due to nonuniformity of attractive forces between electrodes, this embossed pattern permanently changing its configuration. Radiation (light of different ranges, radio and electromagnetic waves, particle streams) passed through screen or reflected therefrom dissipate due to optical nonuniformity. Kind of dissipation continuously varies due to changes in embossed pattern. Segments of conducting layers can be energized obeying different laws including pseudorandom one.

Device for scattering of radiation relates to the field of dispersion of radiation, namely the scattering of electromagnetic radiation, in particular light, radio waves, x-rays, also scattering particle fluxes and others, and can be used in information display systems, radiation protection, masking objects from locations and passive monitoring, create different lighting effects and other

Known deformograficheskie modulator (Revenko V.N., Segal. S.A. Complexes of display devices. "Radio I Svyaz', Moscow, 1985, p.11-14). This device is intended to display information by light leakage in a certain way with the aim of obtaining images on the big screen. On deformograficheskie modulator using irradiation his light from the reference image is generated terrain that corresponds to this image. Powerful luminous flux directed to the modulator and is reflected from it, is scattered on the terrain and on the screen appears the image corresponding to the reference. This device has consistently spaced elements-layers: a first electrode, a deformable dielectric, the second electrode, elastic (elastic) layer, a source of voltage connected to the electrodes. The disadvantage of this device is that to control what asianism must be submitted to the modulator additional control radiation, which significantly complicates the device and narrows the range of its applications.

Also known Layered glare screen on the patent of Russian Federation №1626238. This device will win consistently spaced elements-layers: a first electrode, a deformable dielectric, the second electrode, elastic (elastic) layer, a source of voltage connected to the electrodes. The disadvantage of this device is that the nature of the scattering radiation depends on the radiation and cannot be controlled in a wide range. This device is the closest to the technical essence and the achieved effect of the claimed invention and is taken as a prototype.

Device for scattering radiation contains successively arranged elements-layers: a first electrode having a conclusion (or conclusions) to the supply voltage (or voltages), the deformable insulator, the second electrode having a conclusion (or conclusions) to the supply voltage (or voltages), elastic (elastic) layer, characterized in that at least one of the electrodes is divided into sections, each of which has a separate output for supply voltage. At least one of the electrodes is made in the form of a flexible film.

The invention can be performed in two ways. The first one of the power is s made reflective to radiation, and, the layers from the reflective surface of this electrode is made transparent to radiation. In the second embodiment, both electrodes are made transparent to radiation, layers, ensuring the passage of radiation through electrodes made transparent to radiation.

The principle of the device is based on creating inside the multilayer structure of the terrain. Due to the occurrence of the relief and the emergence of optical inhomogeneity is the dispersion of the radiation falling on the device. The relief is created on the flexible electrode by its deformation. The deformation occurs due to the nonuniformity of the electric field strength between the electrodes (conductors). In turn, the inhomogeneity of the electric field in the space between the electrodes occurs due to the filing of the sections of the divided electrodes of different electrical voltages.

Different voltages are served from a source of voltage, each of conclusions which there is a voltage generated by the given law. On the conclusions of the source can be generated voltage whose values change continuously or discretely pseudo law or appear at random points in time. In this case, inside the relief will be continuously chaotic change that will lead to Slu is inamu the nature of the scattering radiation. This effect can be useful when using the device for radiation protection or concealment.

In the first variant of the device, when one of the electrodes is made reflective, the radiation falling on the device, will be reflected from one of the electrodes is made reflective, and due to the randomness of reflection of the reflected radiation will be difficult to analyze. Thus will be achieved disguise. When reflecting this can be done as a flexible electrode (made in the form of a film), on which is formed a relief, and not flexible. In the first case, the inverse scattering radiation will occur due to the unevenness of the reflective surface and the second due to the refraction of both direct and inverse radiation passing through the deformed flexible electrode.

In the second variant of the device, when both electrodes are made transparent, there will be a scattering effect of the radiation passing through the device due to the different angles of refraction when passing radiation through the deformed layer. If this device is to place a reflective screen, together with it will be achieved the effect of masking. The scattering radiation transparent device can serve the purpose of protection from radiation, for example from the blinding light. The device provide the AET effect of reducing the specific surface incident radiation power.

It is the above basic principles common to both device variants scattering of radiation, comprise the essence of the invention. Inventive concept is that by supplying different voltages creates a non-uniform electric field, which causes the appearance of the relief on the inner layers. Due to the topography of the observed scattering effect of the radiation. The difference between the options is only that in one case scatters the reflected radiation, and the other passing through the device.

In certain cases, the source voltage may file does not change (constant) voltage at different sites, or to apply the same voltage to the portion of the parcel to create a constant not changing terrain. This simplifies the device, but the resulting effect in some cases would be sufficient, for example, to protect the eyes from the blinding light.

Supply voltages on some parts of the electrode(s) can be a source of stress and other laws, different from random. Controlling the distribution of electric field intensity, and with this relief and, therefore, scattering of radiation, it is possible to obtain various effects, for example to send the desired path of the scanning beam or stream of particles,to obtain different lighting effects up to the advertising and illumination.

Creating a managed relief, you can get the desired light image on the screen, i.e. the inventive device can be used in display devices. This principle is based action deformograficheskie modulator, which is the analogue of the invention, which is described above. There the terrain is generated due to irradiation of the modulator by radiation from the cathode ray tube. However, if on different parts of the electrode to apply the appropriate voltage, it is possible to obtain a similar effect on the terrain.

To enhance the effect of dispersion flexible can run both electrodes, both electrodes can be divided into electrically isolated from other areas.

Figure 1 presents a drawing of a variant of the device. Here 1 is the transparent substrate, 2 - conductive layer (electrode), 3 - deformable dielectric, 4 - flexible electrode 5, an elastic layer, 6 - source voltages. Layer 2 is divided into sections, each of which announced its withdrawal from the source of stress.

Figure 2 presents the block diagram of one embodiment of source voltages. Here 7 - power battery pack, 8 - valve, comprising amplifiers-switches 9, 10 - programmable device.

The inventive device operates as follows.

In the initial state, the voltage El is trade 2 and 4 are not submitted. Flexible electrode 4 is not bent, the elastic layer 5 and the deformable dielectric 3 is not deformed. In the initial state may be filed with the voltage on the electrodes, with all the leads of the device connected to the sections are divided into the areas of the electrode is the same voltage. In a variant of the device represented in figure 1, this electrode 2. In this case, between the layers 2 and 4, an electric field. But this field is due to the fact that the same voltage is homogeneous. Therefore, the flexible electrode 4, compressing the deformable dielectric 3, are attracted to the electrode 2, but evenly, and topography within the device will not be created. In both cases, supply the same voltage to the land and its absence in the device inside the device is optical homogeneity, and light scattering does not occur.

When applying different voltages to the sections of the layer 2, the electric field in different parts of the space between the electrodes will be different. Accordingly, different value in different parts of the space will be and electrostatic forces that attract to each other the electrodes. This will result in deformation of the flexible electrode 4 he bent in the transverse direction. This deformation will affect the layers 3 and 5. Inside the device will arise optical heterogeneity. Flux the radiation will fall on the surface, having different angles of reflection or refraction at different points in the space inside the device. This will be a scattering of the radiation.

A similar effect can be observed when light passes through a relief glass.

Disabling voltage electric field between the electrodes disappears. All layers are returned in original condition, under the action of elastic forces of the elastic layer 5, a flexible film 4 is returned to its original state, the deformation disappears and the scattering effect disappears.

The source voltage may consist of a group of amplifiers switches 9 (2)connected to the valve 8, which provides the supply voltage from the battery 7 (power supply can be any, including external) and the control signals from the programmable device 10. As the programmable device 10 may be a computer, or more narrowly specialized electronic device that generates at its outputs signals at a specified, defined by its schema and/or recorded program, the law, including pseudo. The signals from the device 10 serves to control inputs of the amplifiers 9 and those under their control form the output voltage applied to the areas of the electrode, using electrical energy stored in the battery 7.

To the programmed condition is the device 10 may connect an external device. For example, when using the device scattering of radiation in the information display systems to programmable device may be connected to a device that contains in one way or another information that you want to display. Under the influence of this device is a programmable device generates at its output a voltage that will provide relief for displaying a predetermined image on the screen by passing light through the scattering of radiation. In this case, the device will work just as similar as described above, except that the inhomogeneity of the electric field between the electrodes will not be created due to the change of resistance of Fotolia under the influence of radiation, and by feeding on parts of the electrode control voltages.

As mentioned above, one of the electrodes may be reflective. If this electrode 4 (figure 1), layers 2 and 3 must be transparent if the radiation falls below. If the radiation falls from above, it should be made transparent layer 5. Reflecting can be one or both surfaces of the electrode 4. The reflective surface of the electrode is always combined with transparent layers. In the case of applying the reflective electrode scattering effect will be observed in the reflected radiation.

If all the layers are made transparent, the effect Russ is the air traffic management will be in the radiation past through the device.

Divided into sections can be both electrodes 2 and 4. Flexible can also run both electrodes. In the latter case, near the layer 2 from the side opposite to the location of the layer 3 must also accommodate the elastic layer, similar to layer 5.

One way to separate one of the electrodes on areas such as layer 2 (figure 1), can be constructive separation of the electrode is electrically isolated from other conductive parts. This can be done by drawing on a dielectric substrate, the conductive segments in contact with each other. This substrate in this case is technology, but not the functional layer.

Another method of separation of electrode sites is that the sites are virtual, i.e. the physical separation of the electrode on the sites does not occur. The essence of the method is that the layer is physically homogeneous, but due to the changing supply voltages at different points arise the heterogeneity of the distribution of electric charges on its surface, there are electric currents, and, accordingly, the electric field between the electrodes is not uniform. In this case, the supply voltage must be variables.

The third way to create electric is not what narodnosti electrode is what areas are not electrically isolated from each other, but by adding additives in the substance of the electrode in its various areas have different value of electrical resistance.

A special case of the third method of creating electrical heterogeneity represents a fourth method lies in the fact that the electrode is made of a photoconductor. This method is suitable for light emission. Upon the occurrence of light photoconductor in different ways, depending on the light conditions at different points, will change its resistance. Supply voltages on the electrode in different points will cause a change of relief.

The transparent substrate 1 (Fig 1) are not essential features of the invention. They may be present in the device, if it runs in a separate screen that represents an independent structural unit, and to serve the purpose of protection of the inner layers of the device.

The device can be run as part of a protective coating, and in this case the need for the substrate 1 is completely eliminated. For example, the device may enter the glass cockpit or be included in the protective coating of the masked object. The presence of the substrate 1 does not directly affect the achievement of the inventions claimed result.

T is coprostasis layer 2 may consist of tin dioxide. This layer can be applied by spraying 20 wt.% solution of tin tetrachloride in butyl acetate on the surface of the glass at 50°C. Layer 3 of a deformable dielectric material is a mixture of polymethylsiloxane liquids. The elastic layer 5 is made of silicone rubber, elestirilerini polymethylsiloxane liquids. Flexible electrode 4 may be made of metallized film on a Mylar base. Mylar film in this case is a process, not a functional layer.
