Description

j The invention relates to the use of holography in the equipment of theaters, lounges and the like, can be used both in various light-musical devices and in stand-alone toys with keyboard or potentiometric control.

iHa drawing shows a device for (Implementation of the proposed method (vapiant for phase reflection reflector rparjflMbi).

The device comprises a housing 1, in which a flexible plate 2 of thermoplastic is fixed - a carrier of reflective phase holograms with sections 2-1, 2-2; 2-3, on which holograms are recorded in the red, green and blue light of the laser, respectively, and rods 3-1.,. 3-n of ferromagnetic material, the first end of each of which is associated with the corresponding output of the solenoid 4-1. ..4-p, the input of each of which is connected to one of the outputs of the driver 5 of the control signals, and the second ends of each of the rods 3-1 .. are attached to the flexible plate 2.

The device operates as follows;

Light waves during reflection from the carrier of hologram 2 change their phase in accordance with the thickness of the material at the reflection point, in general, the phase of the reference wave front changes from point to point on the surface of the holograms, the reflected light waves interfere, and amplifying interference occurs only for a certain colors. As a result, at the output of each hologram, a wavefront is formed that accurately reproduces the wavefront, which was created by reflection from the object during telegraphy, i.e. there is a three-dimensional image of the object. Since there are three holograms in different colors in sections 2-1, 2-2, 2-3 of the medium, the images from these holograms overlap and, as a result of the partial addition of colors, a multi-color three-dimensional image of the object appears.

Resizing and spatial distribution of one of the color components of the image is made in the presence of a control electric signal in any of the 4-1 ... 4-p solenoids, which occur in the corresponding

the rod 3-1 ... 3-n magnetostrictive phenomena lead to a change in the length of this rod and to the bending of the portion of the flexible hologram carrier plate 2 fixed to the rod (e.g., portion 2-3 with the hologram in blue light). In this case, the change in the size and spatial arrangement of the part of the image obeys the formulas of concave and convex mirrors (depending on the direction of bending), and since the remaining part of the section 2-3 of the plate 2 that is still stationary continues to form the same image in the same place and the transition from the curved section directly, gradual (continuous), then the image will be integral, continuous, deformed (stretched or compressed). By moving one of the color components of the image according to the law of complementary colors, the color of the image also changes (for example, if a blue component is taken out of a point in a white image, this point in the image will turn orange, and next to the blue point ) Note that when the spherical segment is shaped by deformation of the plate 2, the image is proportionally reduced or enlarged depending on the sign of the direction of deformation.

The use of magnetostrictive phenomena in ferromagnetic rods 3- 1,., 3-p allows fine adjustment of the bending of the plate 2. To provide a more significant bending of the plate 2 in order to obtain a significant measurement of the shape and size of the image, the device can be retracted 4-1.,. 4-solenoids under the influence of the magnetic field of these solenoids and returning to the initial state by supply, by the action of the elastic forces of plate 2 (or by means of compression springs), ferromagnetic rods 3-1 ... 3 -n, for human about not only necessary to be secured the second ends of the rods in the solenoids 4-1 ... 4-n.

With the simultaneous deformation of the flexible plate 2 at several points, including those belonging to different sections 2-1 ... 2-3 (each in its own size), the image of the object will take on a bizarre shape with iridescent colors, with a smooth dynamic deformation of the plate at different points will occur and a smooth dynamic change in the shape and color of the image. A large number of deformation points in combination with various possible deformation values at each point will allow creating an almost unlimited number of different sequences of image changes - color and space melodies. These possibilities of the claimed method and device for its implementation are even wider, given that holograms can reproduce more than a million shades of brightness, in addition, it is possible

and varying the brightness of the reference wave — the brightness of the image is higher, the more intense the illumination.

The proposed method and device allow the use of various types of holograms, but it seems most promising to use volumetric

5 reflective Denisyuk holograms or phase holograms, allowing to restore the image in white light, including normal daylight or sunlight.

0 This makes it possible to simplify the use of images, since in this embodiment, the use of lasers is required only when recording holograms. In addition, thermoplastic sheets with written holograms

5 can be replicated by stamping with. power of the metal matrix, which makes it possible to significantly reduce the cost of the device and use it, for example, in domestic spatially color musical installations.

It is also possible to use interchangeable plates with holographic records of various objects as a basis for obtaining various classes of dynamic

5 melodies of color and space.

The most effective is the use of holograms of semitransparent objects with internal inclusions that give when turning or changing the angle

0 light glare (for example, with chipped glass, crystal faces).

The method and device provide the necessary capabilities for easily controlling changes in the coloring, shape and size of the image. Control signals can, for example, be recorded on a tape recorder or output from the microcomputer at any acceptable speed, it is possible to control using keys or potentiometers.

0 To control the operation of the solenoids, any known channel-based control signal generation circuitry may also be used.
