Image reproduction is performed by electron-optical scanning on a matte screen, viewed separately by moving spectral filters in the frames of the separate frame observation unit, which includes an IR receiver, a pulse shaper and a piezoelectric motor with a shaft on which frames with rotary mesh filters mounted for rotation are mounted with a frequency of 12.5 Hz. The disadvantages of the prototype are: you cannot use the system for driving combat vehicles, the way to view stereo frames separately using mechanical rotation of the filters is also not suitable when driving, insufficient image brightness on the screen when the frame is scanned with only two lines at a time.

Each normalizes the output of six analog video signals of the right / E _RP , E _GP , E _VP / and left / E _RL , E _GL , E _VL / stereo frames. ADCs convert analog video signals to 8-bit codes. The sequential issuance of codes first with the ADC 4, 5, 6, then with the ADC 7, 8, 9 is performed by the trigger 12 and the keys 13, 14. Pulses of the frame frequency of 50 Hz from the fourth output of the synthesizer 11 frequencies are fed to the input of the trigger 12, the signal from the first output which is opened by the first key 13, which transmits 24 MHz clock pulses for 0.02 seconds of the right-frame / odd period to the ADC clock inputs 4, 5, 6, the codes of which are sent in parallel to the drives 15, 16, 17 of the codes, respectively.

Photoelectric converters 1 and 2 work identically. The lens 37/2 / creates a color image of the right frame in the focal plane in which the reflector of the first piezoelectric deflector 38 is located. The reflector has a width of 0.02 mm, a length of at least 12 mm / 0.02 × 600 /. The dimensions of the deploying element are 0.02 × 0.02 mm. According to the control voltages (Fig. 3/) from the amplifier 39, the piezoelectric deflector 38 vibrates the end face with the reflector relative to the first reflector at the end of the second piezoelectric deflector 42, scanning the image line of the right frame. The lens 46 creates a color image of the left frame in the focal plane in which the reflector of the third piezoelectric deflector 47 is located.

A similar process takes place rays from the second reflector of the piezoelectric deflector 42 and enter the photodetectors 74, 75, 76. From the preamplifiers, analog video signals are received: the right image to the inputs of the ADC 4, 5, 6, the left image to the inputs of the ADC 7, 8, 9. The ADCs have one conversion principle consisting in the scanning of the beam (Fig. 4/) from the LED 84 by the reflector of the piezoelectric deflector 81 along the plane of the entrance pupils of the photodetectors of the array 87 of the multi-element photodetector, the light pulse is converted into an electrical signal that excites one of the input buses of the encoder 88, which gives the code of the instantaneous value of the input video signal, the conversion is performed with a sampling rate of 24 MHz.

Blocks 108, 109 each include 300 blocks 110 _1-300 registers. In the third period of the frame, codes are sent from block 109 and codes are accumulated 600 lines by block 108. So, alternating, the process repeats. Blocks 110 registers work as follows. All keys of blocks 110 in the initial state are closed. With the arrival at the input of trigger 107 of the first frame pulse of 50 Hz from the first output of the trigger, the pulse opens in block 110 ₁ / block 108 / first key 111/11 / which transmits 24 MHz clock pulses to the pulse distributor 115.

The pulse from the 800th output of block 115 closes the key 111 and opens the key 113, which transmits 24 MHz pulses to the input of the pulse distributor 117. The clock pulses from the outputs of block 117 are sequentially fed to the first control inputs of the bits of the registers 122 _1-8 , the first / information / inputs of which receive the signals of the bits of the codes of the second line, starting from the 800th count of the line to the first, because the scan of the second line goes counter to the scan of the first line / Fig.6/. The pulse from the 800th output of block 117 closes the third key 113 and enters the first control input of the key 111 into the next block 110 _{2 of the} registers as the first output control signal, the key 111 opens, the process of accumulating codes in registers 119 _{1-8 is} repeated in block 110 ₂ , 122 _{1-8 of the} third and fourth lines. Identical processes take place in the following blocks 110 _3-300 . As a result, for the period of the first frame, all the registers of the drive 108 codes are filled with codes of 600 lines of an odd frame. In the period of the second frame / even /, the registers of the drive 109 codes of the even frame are filled in the same way with 600 line codes. At the same time, the output signal from the output 1 of block 110 _{300 is} sent to the fourth control inputs of blocks _1-300 and in _parallel and opens the second keys 112 in all blocks _{110-300 of the} store 108 of the odd-frame code. Signals U _vyd 4 MHz through public keys 112 enter blocks 116, signals U _vyd from which are sequentially fed to the second control inputs of all registers 119 _1-8 in blocks 110 _1-300 simultaneously issuing codes 300 odd lines / 1, 3, 5. ..599 / from drives 108 codes / drives of codes 15, 16, 17 / into blocks 18, 19, 20. Each pulse from the 800th output of block 116 goes to the input of the counter 120 pulses, closes the key 112 through the diode and opens the fourth key 114, the output of which 4 MHz pulses are fed to the input of the fourth pulse distributor 118. The signals from block 118 are sequentially fed to the second control inputs of the bits of the registers 122 _1-8 and give, starting from the 800 code / from the 800th bit of the registers /, the codes of the second / even / line. The issuance of codes 300 even lines / 2, 4, 6 ... 600 / goes in parallel with 300 blocks 110 of the drive 108 codes of the odd frame. After issuing the codes of the second line, the pulse from the 800th output of block 118 / in all blocks 110 _1-300 / goes to the input of the counter 123 pulses, closes the key 114 through the diode and reopens the key 112. The second output of all 300 odd lines to blocks 18 follows , 19, 20. Then the process of issuing 300 even lines is repeated and so on 50 times: 50 times the codes of the odd 300 lines are issued and 50 times the codes of the even 300 lines are issued. With the arrival of 50 counting pulses in the counter 120 and 123, the code 110010 is normalized, which is decoded by the decoders 121 and 124, the output signals from which close the keys 112 and 114. The signal from the decoder 121 and 124 resets all the bits of the registers in 300 blocks 110, and the drive 108 odd frame codes ready to receive third frame codes. During the third frame period, the identical process of issuing the second row code codes from the drives 109 of the even-frame codes in blocks 15, 16, 17 and filling in the codes of the rows of the third frame of the registers in the drives 108 of the odd-frame codes follows. So, alternating, the processes go on continuously. Codes of 300 lines of a color signal of R outputs 1-2400 / 300 × 8 / are supplied in parallel to a block of 18 pulse amplifiers, codes of 300 lines of a color signal G from 1-2400 of outputs are simultaneously sent to a block of 19 pulse amplifiers, codes of 300 lines of a color signal B from 1 -2400 outputs in parallel to the block of 20 pulse amplifiers. Each of the blocks 18, 19, 20 contains 2400 pulse amplifiers with a response time of 18 ns [5 p.128]. The outputs of the pulsed amplifier units are connected to the corresponding inputs of their 300 emitters in the radiation modulation unit 21 / Fig. 8/. Each emitter includes 24 LEDs. For radiation, each LED is read out by a signal from its pulse amplifier. 300 emitters include 7200 LEDs: 2400 - red radiation, 2400 - green and 2400 - blue radiation, HL MP type LEDs are used by Hewlett-Packard company [6 p. 71]. For red radiation, LEDs HL MP-AL00 with a light intensity of 0.4 cd, with a wavelength of 0.59 μm at a current of 0.02 A [6 p. 71] are used, for green light-emitting diodes HL MP-AM00 with a light intensity of 0, 8 cd, wavelength 0.526 μm at a current of 0.02 A, for blue radiation - HL MP-AB00 LEDs with a light intensity of 0.3 cd, wavelength of 0.475 μm at a current of 0.02 A. The brightness modulation of radiation is carried out by switching on the LEDs in the emitter 103, respectively, the weight of the discharge in the code according to table 1.

The total emission of three-color LEDs from the emitter is mixed when the radiation is focused by the lens 104 / Fig. 8/ and introduced into the input window of the focon 105, which projects the radiation onto the reflector of the piezoelectric deflector 29 in a circle with a diameter of 0.02 mm. The length of the reflector of the piezoelectric deflector 29 is: 0.02 mm × 600 _lines = 12 mm. 300 emitters give 29300 circles on the piezoelectric reflector reflector. The brightness, saturation and hue of the resulting color of the circle on the reflector is determined by the total energy and the mutual ratio of the three colors. The total luminous intensity of one emitter, given that the LEDs of all colors have a light intensity of 0.3 cd / blue LED / is: 3 · 0.3 cd / 1 + 0.5 + 0.25 + 0.125 + 0.0625 + 0, 03125 + 0.0156 + 0.0078 / = 0.9 cd1.992 = 1.7928 cd,

where: 3 - the number of colors in the emitter,

1-0,0078 - binary digit coefficients in 1-8 code bits. Total luminous intensity from 300 emitters: 1.793 cd · 300 = 537.8 cd.

At 100 repetitions of sweeps per frame: 537.8 cd · 100 = 53780 cd.

Taking into account losses during projection from emitters to screen 33, the averaged maximum possible radiation power is 10 times: 53780 cd: 10 = 5378 cd.

The resolving element on the reflector of the piezoelectric deflector 25 is taken 0.04 mm, the length of the reflector on it will be: 0.04 mm · 600 = 24 mm. Taking the magnification of the image magnification by the projection lens 32 by 10 times, the screen sizes will be:

horizontally 10 · / 0.04 mm · 800 _readout / = 320 mm,

vertical 10 · / 0.04 mm · 600 _lines / = 240 mm,

diagonally 400 mm or 15.7 ″ inches. 0.04 mm circle resolution element on the piezoelectric reflector reflector 25. The perception of a three-dimensional image on the screen with an image radiation power of 5378 cd creates the driver the necessary conditions for viewing the driving route when driving a car.

System operation.

When moving forward, the driver on the switching unit 3 includes a photoelectric converter 1/1 /. The analog color video signals of the right and left frames in series are fed to the inputs of the ADC 4-9, which convert the analog video signals into 8-bit codes. Sample conversion of 24 MHz. Codes with ADCs 4–9 in parallel form enter the corresponding codes 15, 16, 17, which in the first frame period accumulate codes of the first frame, in the second frame period, the accumulated codes of the first frame are simultaneously in groups of 300 lines in parallel, at first odd, then even issued with repetition of 50 times per frame through the pulse amplifiers of blocks 18, 19, 20 in the emitters of the block 21 modulation of radiation. In parallel, the drives 15, 16, 17 codes accumulate the codes of the lines of the second frame, after issuing the codes of the first frame, the codes from the blocks 15, 16, 17 of the second frame are collected and the codes of the next and third frames are accumulated. This process is continuously repeated. 300 emitters 103 _1-300 , block 21 convert the binary codes of the samples at the same time 300 lines into modulated by the brightness of the radiation projected onto the reflector of the piezoelectric deflector 29, reflecting from which the radiation goes to the reflector of the piezoelectric deflector 25 located in the focal plane of the projection lens 32, performing horizontal scanning simultaneously 300 lines, the projection lens 32 projects the image of the frames of stereo pairs on the matte screen 33 with a magnification of 10 times / possible and more /. The 3D image is perceived through ZD glasses 36 with an IR receiver on the frame, which receives control signals from the IR transmitter 34 located above the screen 33. The control signals for the IR transmitter are 25 Hz clock pulses coming from the second output of the synthesizer 11 frequencies . To change the direction of the car’s movement in the opposite direction, the driver does not need to turn the car 180 °, he turns on the photoelectric converter 2 on the switching unit 3, on the screen 33 the image of the space of the reverse movement is reproduced in volumetric representation. The driver gets rid of the observation of the terrain through a narrow viewing gap that limits the viewing sector, the driver’s location does not depend on the direction of movement, the application of the inventive system will increase the sharpness and speed of maneuvering the combat vehicle, i.e. reduce the degree of its defeat in combat conditions.
