Mirror for p the th image, for example, to obtain the actual image looking in the mirror man.

Know the true mirror display, i.e. the mirror to obtain the actual image, US patent 5625501, but this mirror forms an image in the middle of which is preventing vertical strip, and the slightest deviation from 90 degrees of the angle between the two components of this mirror is a flat mirror causes significant distortion of the image.

It is also known the true mirror display, i.e. a mirror for direct, real images in patent WO 96/30785, but this mirror is bulky, and in an embodiment using two perpendicular flat mirrors it has the same drawbacks as the mirror in patent US 5625501.

The closest in technical essence is a mirror of the positive display, i.e. the mirror to obtain the actual image, patent CN 1056173. This mirror is very simple, cheap, the thickness may be closer to the flat mirror and convenient for practical use, but because it generates undistorted direct real image only at a certain distance from it, moreover, is whether this region of space, which must be the eye of the observer, i.e. an observer is almost impossible to see the actual image without distortion, i.e., with high quality.

The aim of the invention is to reduce distortion of the actual image seen by the observer, i.e. to improve the quality of the image.

This objective is achieved in that the mirror to get the real image containing at least one concave reflecting surface having the form of a bent plane, or in addition, additionally containing at least one element, each convexity or concavity which has/have the form of a folded plane, or a special lens, or containing at least one planar reflective surface and at least one lens, each convexity or concavity which has/have the form of a folded plane, or a special lens, further comprises device location is the best point or area of looking in the mirror, and location relative to the mirror, when in which the eye of the observer, the observer sees the image is undistorted. The device location is the best point or area from which that can optically determine the best location of the point or area of looking in the mirror. The device location is the best point or area of looking in the mirror can contain shaper signal/signals/instructions/instructions, an input connected to the output of the measuring range or latitude. Measuring range or latitude may be ultrasonic.

INFORMATION CONFIRMING THE POSSIBILITY OF CARRYING OUT THE INVENTION.

In Fig.1 shows an example of a simple, cheap and shape close to a flat mirror to obtain a valid image from the optical device location is the best point for looking in the mirror. Such an embodiment is very convenient, for example, pocket mirrors. This mirror contains a biconvex lens 1, each bump which has the shape of a bent plane, and on its first side caused noteu plane. In principle, any side convex lens may be flat, i.e., the lens can be adenovirally, but you'll need a large degree of convexity of the convex side of the lens, and if the reflecting layer of the substance to be applied to the flat side adenovirally lens, the reflecting layer of the substance on the merits will be flat reflecting surface, which will require an even greater degree of convexity of the convex side of the lens and decrease the degree of plane just mirrors. In the center of the upper part of the convex lens 1 on the side, free from the layer of reflective material 2, there are three visual label: the label of induction 3, and the first 4 and second 5 tags for the desired image boundaries label guidance. These three visual cues together with the convex lens 1 and the layer of reflective material 2 performs the function of a device's location is the best point for looking in the mirror. Marks 4 and 5 are removed by horizontal lines in different directions from the label guidance 3 at a certain distance d, the choice of which depends on the distance of Vopt, i.e. the distance between the mirror and the observer, where the observer sees the actual image without distortion (since Voptdepends on the focal length in this case is the distance between the layer of reflective material 2 and the label guidance 3).

The principle location is the best point for looking in the mirror is that by adjusting the location of the mirror relative to the observer's eye, or adjust the location of the eye of the observer relative to the mirror, to achieve alignment of the lateral boundaries of the image in the mirror label guidance 3 respectively labeled the required boundaries of the image tag pointing 4 and 5 (which itself marks 4 and 5 deposited on the convex lens 1, and not with their images in the mirror). Since in this case the label of induction 3 is closer to the mirror than the focus F of the mirror and the observer is farther than the focus F of the mirror, removing the observer from the mirror he sees increase the horizontal size of the image in the mirror label guidance 3 and decrease the horizontal size of the image in the mirror. This has been proven experimentally. In the figure 1 in the horizontal plane shows the image tag pointing 3 when the above combination. This image is constructed as the image in Bogota the mirror, equivalent to the set of convex lens 1 and a layer of reflective material 2. The distance d, which removed the marks 4 and 5 from the label guidance 3 selected in this way, th is s and vertical dimensions of the actual image looking in the mirror man is true, ie, formed undistorted actual image, as shown in Fig.1 point And the best point for looking in the mirror.

In other embodiments, the execution of a mirror to obtain a valid image described in the restrictive part p. 1 claims, for example, patent JV 1056173, implementation and operation of the optical device location is the best point for looking in the mirror can be similar to those described above. If the design of the mirror lenses are not available, visual cues, at least the label guidance, should be placed on any mount at some distance from the reflective surface.

The optical device of the location of the best areas for looking in the mirror may differ from the above-described optical device location is the best point for looking in the mirror, for example, the presence instead of each of the marks 4 and 5 corresponding pair of labels indicating the boundaries of permissible positions of the lateral boundaries of the image in the mirror label guidance 3. When the lateral boundaries of the image in the mirror tags hover between 3 marks indicating the limits of their allowable position, i.e. when nahozdeniya does not exceed allowable values.

In Fig.2 shows an example of run-structural diagram of an electronic device, the location of the best point or area of looking in the mirror, which can be applied in any mirror to obtain a valid image described in the restrictive part p. 1 claims.

This unit is the best location of the point or area of looking in the mirror contains connected in series: measuring range 6, designed for signal range, i.e., the signal carrying the information about the distance between the mirror and the observer, or the locator 7 for building in addition to the signal range of the signal azimuth, and/or signal elevation angle, i.e. for the formation of not only signal range, but also signals that carry information about the angular coordinates of the observer relative to the mirror; shaper signal/signals/instructions/guidance 8 (for example shaper light signals or shaper voice guidance), designed for signal/signals/instructions/directions on how, in what direction or how to move the observer to get into the best point or zone for looking in the mirror, i.e., to the point and Itel range 6 or locator 7 may be ultrasonic, in which the information about the distance is determined by the delay time of the received ultrasonic pulse relative rejected.

Operates electronic device, the location of the best point or area, watching in the mirror as follows.

Measuring range 6 or locator 7 generates the signal/signals, bearing/bearing information about the position/coordinates of location of the observer relative to the mirror. These signals are sent to the shaper signal/signals/indications/indications 8, which can be applied, for example, the shaper light signals or shaper voice instructions, which, depending on the differences of the coordinates of location of the observer and the best point or area of looking in the mirror forms a correspondingly light signals or verbal instructions about what direction or how to move the observer to get into the best point or zone for looking in the mirror.
