    The light incident upon a lenticular parallax panoramagram variable aspect display device (10) is imaged upon the object field (20) and then distributed in part across portions of the object field (20) outside the images. Adjustment is made for the rate at which'the display changes as a function both of the rate of movement of the viewer past the display device (10), and of the instantaneous absolute angular position of the viewer with resepect thereto. Adjustments can also be made for paralax, lens circular aberration at off-center viewing angles, differential thermal expansions within the device (10), and display changes due to changes in ambient conditions. Each lens element (18) is preferably provided with its own exclusive object field (22).

    The invention relates to lenticular paralactic panorama images and is intended for obtaining important visual information, changing in accordance with the method of observer
    The purpose of the invention is to improve the image quality by eliminating parallax.
    FIG. 1 shows a DD1I device displaying information when used as a road sign; in fig. 2 the same, transverse section.
    The device t for displaying information in the form of alternating: -5xs symbols of road or navigation signs contains the supporting panel 2, the front surface of the 3 supporting panel, the Lars Helmet partitions 4, by / for; subject field, raster element 6 of the symbol, a cylindrical lens 7, angle 8 of observation, diffusers 9 ,;
    When used as; A road sign device 1 for displaying information in the form of alternating symbols, road signs or road signs (Fig. 1) is installed, for example, on a highway approaching a curved section. The device is intended to display two kinds of road sign symbols.
    When the car arrives and the device to the device 1 and its driver is in position A, the device is displayed to the driver for the driver 1. View at point A. When the car is transferred to the point BE, then the symbol Bi will be displayed at the point 1 at. Accordingly, when the car moves the driver to position C, device 1 will display the symbol View at point C.
    According to the embodiment of the design, the image shown in FIG. 2, the device contains a plurality of cylindrical lenses 7, however, spherical lenses may be used, as well as other shaped plastic elements. When using lenses with ribs: l cross-section, undesirable aberration is possible if the lenses are too wide in comparison with focal length. In a number of cases when a large width or smaller focal length is required, for example, spherical lenses can be used to increase the working angular width of the system.
    32
    To make the lens resistant to mechanical damage, reinforcement can be introduced into its design.
    Behind the cylinder 1-gi1 Shi lenses 7 in their foci are substrates 5 of the subject floor, separated by parallel partitions 4, fixed on the lidding surface 3 of the supporting panel 2. Each substrate 5 of the subject floor corresponds to a specific cylindrical lens 7 and is positioned so that the beam of light, on the cylindrical lens 7, is directed to the corresponding substrate 5 of the subject field, Each substrate 5 of the subject field extends to a value corresponding to the limit observation angle 8. On the kg-base substrate 5 of the subject floor, raster elements of 6 CrWBola are applied, conjugated with various 1-g-1ngi viewing positions and distributed on the substrate 5 of the subject floor so that
    so that each such element was selectively visible to the observer through the equipment made up of and; il1-shdr cells of their 1: 3: 7 Therefore, when the observer changes the angular position,
    change of the image visible to him; keny. By appropriately arranging the elements 6 pa of the substrates 5, the subject of 1-x fields is achieved by changing the image or indicating some part of the surface: a crane composed of lenses 7.
    It should be noted that all the elements of the 6th symbol, visible through one of the cylindrical lenses 7, are enclosed in
    within the corresponding specific substrate 5 subject field.
    According to FIG. 2, ash substrates 5 are provided for pre 1t summer, the curvature of which is such that the raster elements deposited on them
    The sixth waves are located within the focus of the corresponding cylindrical lens, regardless of the angle 8 of the eye. In the case of cylindrical lenses
    The 7th shape of the UNDERFAST is also cylindrical When using lens elements of a different shape, the lens fields are given the appropriate configuration. The curved surfaces of the substrates 5 shown in FIG. 2 can be made of molded plastic or sheet metal. It is also impossible to use a lens
    structures that provide curvature correction floor.
    Instead of gently curved surfaces of the substructure 5, in order to correct the subject field to match the foci of the lens elements, it is also possible to provide a stepped shape of the substrate 5 composed of flat supporting surfaces. Such a structure ensures that an exact correction can be made only in a limited number of angles. 8 Observations J However, within each viewing phase, the deviations can be made negligible, In such cases, this design can facilitate the implementation of the substrate 5 subject field
    The parallax correction caused by a change in the observation angle 8 is performed by gradually changing the interval or width of the various raster elements 6 of the symbol from one substrate 5 of the previous field to the subsequent across the entire width of the device 1,
    The description of the relative widths of the 6-character elements to compensate for parallax is given in the event of a simultaneous change of the image throughout the device 1, however, it should be borne in mind that sometimes a non-simultaneous change of the image on the sign is desirable. As an example, refer to a directional boom, alternately lengthening and contracting. In this case, the described principles of adjusting the width of the various elements of the image are also used in order to deliberately obtain parallax and anti-parallax. Due to this, the desired speed and degree of movement of the visible image is achieved.
    Thus, the width of the raster elements 6 of the symbol varies both within each substrate 5 of the subject field, and when moving from one substrate 5 to another.
    When working at night time, the illumination of the device 1 is almost entirely realized at the expense of automobile headlights, roughly approximating point sources. Optical constructions of cylindrical lenses 7 focus the headlights into relatively perverse areas. t, eG focus the light from a compact source like headlamps in a narrow strip on the substrate 5. Therefore, the light from the left headlight focus 5

    on substrate 5 in one place, and matchmaker from the right headlight in another place. substrate 5.
    As a result, the corresponding elements of the image seem to be brighter if the driver of the car is in the same direction as the headlight, and it’s quite dark, if the driver’s line is located between the heading lines and the heading. Since last; the situation is the most frequent case, the lack of luminance can be compensated by dissipating the illumination of the sign so that the elements of Element 6 always have enough light to see the image as an observer.
    In order to increase the overall brightness, the substrate 5 of the predetermined field, installed behind the lenses 7, is made of an optically transparent material, the darker areas — elements 6 — are placed on the substrate 5 of the subject field and made of an opaque material, for example paint. At a distance behind the substrate 5, diffusers 9 are installed behind the foci of the lenses 7. When light passes through the transparent areas of the substrates 5 and beyond the foci of the lenses 7, it diffuses and illuminates a relatively large portion of the substrate 5. Light reflected from the diffuser 9, :, - Lives to illuminate the substrate 5 of the predicate field at observation angles of 8, different from the angles of the initial incidence of light.
    To obtain the required illumination, you can use a diffuser 9 of glass beads. In this case, the light is focused inside the ball near its opposite side. The back side of the ball is embedded in or covered with reflective material, so the light returns to the side from which it came. With an ideal spherical reflector, when the diameter of the ball is identical to its focal length, the light reflected from the back side of the ball returns and is collimated so that it returns exactly in the direction it came from.
    In practice, the diameter of the sphere is usually not exactly equal to the focal length, and the spherical aberration is large. Therefore, the image formed on the back surface of the ball is not a point, but a significant area. If the reflective material that is targeted (for example, opaque plastic) or that it is covered with (for example, paint) is a diffuse reflector, then the light () fuzno returns from each point of the image; appear after the internal reflection in it with significant angular scattering, refer to the direction of its initial padapil and through the area of the front surface. As a result, ziachite. In the area of 1 square 5 occupied by balls appears illuminated.
    Usually, glass balls are limited only to those areas of image elements that should be seen. By hanging balls to dark areas, a certain amount of light returns, since dark areas are usually not perfect1; o black. As a result, the contrast between light and dark areas of the sign is worsened when the ear is blunt.
    The image on the information display device can carry a message or a graft-sh message, and can also be simple in the form of an area of one color; sweat, she with ten mi. Two devices with alternating yellows and blacks can be placed on the sides of a typical traffic sign. The rasters of the elements of each device can be arranged so that one device is yellow and the other black, and vice versa. Due to the choice of the correct speed of change from a sample of scientific research institutes on the device and compensation of parallax and speed of change of the viewing angle in accordance with. By the methods described, an effect similar to the action of electrically flashing lights is achieved, installed next to the sign. Advantage of the device
