The device works as follows.

In the playback mode, the voltage at the input 26 of the synchronization unit 22, as well as at its outputs 28 and 29, is zero. In the switch 24, the transistor switches 71 and 73 are closed, the emitter follower 70 is completely open, and at its output 37, the voltage is almost equal to the anode voltage U, of the source 17. In the switch 25, the generator pulses 16 clock pulses pass without changing to output 42 through elements AND 67 and OR 69. In this mode, if there is a control pulse at input 5 of control unit 4, information signals from a computer in a sequential code through a converter of 2 signals arrive at block 3 of the buffer memory, where the arrays of the displayed information (for example, in the form of pages) and parallel codes are formed to include the key elements of block 7, synchronously with the inclusion of the corresponding key elements of block 12. Synchronization unit 6 carries out the alternate inclusion of key elements of block 12. At the same time, on the electrodes of rows I1 matrix screen 1, corresponding to bright parts of the image, from the key elements of block 7, the anode voltages of V turn on, and on the electrode of column 15, corresponding to the reproduced image column, comes from the key element coagulant unit 12 zero voltage.

A cross section of the switched-on row and column electrodes with zero voltage causes gas discharge to glow, and an image frame is reproduced on the screen. In order to create a flicker-free image, synchronization unit 6 repeats frame playback at a frequency of 50-70 Hz. The required frequency of sweeps sets the generator 16 clock pulses.

The update of the reproduced information occurs when the control playback pulse arrives at the input 5 of the control unit 4.

The cycle of recording information on a photosensitive medium occurs as follows.

Through the first input 26 of the synchronization unit 22, a positive control write pulse is applied to the 5-input of the flip-flop 57, which is in the state o. From inverted trigger output 57, signal 1 arrives at the first input of element 58. At its second input, input 27 of unit 22 receives sweep pulses from the input of the last key element of block 12. The first sweep pulse after the arrival of the write pulse control at the moment | sets flip-flop 57 to state 1. At the same time, signal O appears on the inverse output of flip-flop 57, the next sweep pulses and pass through the element 58 and flip-flop 57 remain on until the reset signal arrives at input I. The signal I from the output of the flip-flop 57 is fed to the output 28 of the block 22 and starts with a positive 4FONT one-shot 60, which produces a positive delay pulse of duration 1, oE The negative edge of the delay pulse starts the pulse shaper 61. Its output impulse arrives at the b-input of the second flip-flop 59. At the trailing edge of the next sweep pulse from the last key element of the block 12, the flip-flop 59 is transferred to the state 1 at the moment -i, and the output 1 appears at the output 29.

The control signal 1 is fed from the output 28 of the block 22 to the input 35 of the switch 23 and, through the inverter 64, closes the element AND 63 for control reproduction pulses. This interrupts the flow of new information. Control signal 1

51

output 28 of unit 22 is fed to control input 31 of registration unit 21 and turns on a controllable drive of a tape drive mechanism 56. The movement of the photosensitive medium 55 begins. Control signal 1 from output 28 of block 22 is fed to input 38 of switch 24. the time ij until the occurrence of signal 1 at output 29 connected to input 39 of block 24, element 75 is in state 1, transistor switch 71 is open, emitter follower base 70 is connected via key 71 to zero, and anode voltage at output 37 and common bus 8. Power key elements ntov unit 7 is close to zero. At this time, the tape mechanism accelerates, the light modulator is closed and information is not recorded on the photosensitive medium. I

The occurrence at time tj of the delayed control pulse 1 at the output 29 of the block 22 leads to the closing of the transistor switch 71. At the same time, the switch 73 opens and the voltage 37 is set at the output 37. The control signal 1 from the output 29 is fed to the input 43 of the switch 25. At the same time, the And 67 element is closed, and the And 66 element is opened for positive pulses. The output of the switch 42 through the frequency divider 65, the element And 66 and the element OR 69 receive clock pulses of a lower frequency,

At the moment -t, recording of information on a photosensitive medium begins. The recording takes place in columns, starting from the first, since moment 2 is associated with the end of the previous frame of the image. The write speed is set by the lower clock frequency. The anode voltage Ug is set below the ignition threshold of the gas discharge matrix screen to eliminate the additional voltage drop on the anode key elements due to the discharge current.

The voltages from the outputs 10 of the key elements of the block 7 through the information inputs 30 of the registration block 21 are fed to the linear electrodes 49. The electric field between the electrodes 49 and the transparent conductive coating 52 controls the light-modulating

49. 6, the medium 50, which modulates the degree of light of all the light (e.g., phase light), the cylindrical lens 77 of the objective-anamorphic 53, forming which is parallel to the linear electrodes 49, projects the light-modulating medium- 50 onto the carrier 55. The cylindrical lens 78-with forming, - perpendicular to the linear electrodes 49, together with the collimator 45 forms a light column on the photosensitive medium 55 perpendicular to the direction of movement of the carrier. The optically coupled optical readout elements 46 and 54 convert the original light modulation into intensity modulation. As a result, the luminance of the elements of the light column corresponds to the luminance of fragments of the image column, which is currently being output from block 3 of the buffer memory. The speed of movement of the photosensitive carrier 55 is associated with a scale with a reduced frequency of clock pulses and a l-size image of a column. This achieves the correct format of the recorded image. The write cycle continues until ij of the end of the sweep pulse at the input of the last key element of block 12. At time i, the output of the pulse former 61 of the block 22 has a signal O and the trigger 59 is switched by the falling edge of the sweep pulse from the input 27 to the o state. On the trailing edge of the trigger pulse 58, the pulse shaper 62 generates a positive reset pulse, which causes the trigger 57 to state O. At this point, the write cycle ends and the device goes into playback mode.

In a device in a light modulator, for example, electrically controlled PTSL ceramics (polycrystal of zirconate - lead titanate Pb (Zr, Ti) 0 doped with lanthanum) or an electrically controlled deformable elastomer layer 50-100 in thickness can be used as a light-modulating medium. um The length of the linear electrodes and the gaps between them is 50-100 microns.

In the case of PZTL ceramics, the linear electrodes are in electrical contact with its surface. Elasto7

the measuring layer is located at a distance of 20–30 µm from the linear electrodes. The control voltages in both cases can be 100-150 V. In the modulator with an elastomer layer, the even linear electrodes are connected to the information inputs 30 of the block 21, and the odd electrodes are connected to the zero output 32. The elements of the optical fusion in the case of PLCT - ramics are polarizers, and in the case of an elastomer layer - lattices of slits parallel to linear electrodes and optically conjugated with a cylindrical lens 77 half-period shift. As a photosensitive recording medium For example, Ufa photo paper, used in ultraviolet

YOUR registration or film used for microfilming.

The speed of these light-modulating media, the sensitivity of photographic materials and the use of mercury discharge lamps as a light source provide a recording speed of more than 10 columns per second. Thus, the minimum recording time of a frame of 100 columns reaches 0.1 s. Given the inertia of the tape drive mechanism in order to save the recording media, it is advisable to increase the recording time up to 2 s.

In this case, the frequency divider 65 must have a multiplicity of 100: 1, the pulse width of the imaging unit 61 is 25 ms, and the imaging frequency of the imaging unit 62 is 1 ms.
