Abstract:

PURPOSE: To provide an image information recorder and an image information reproducing device capable of selectively recording and reproducing an image repeatedly appearing at a specific cycle.

CONSTITUTION: A high AC bias voltage whose frequency is the same as that of spark discharge is impressed on a PROM element 16 by a current detector 12, an amplifier 13, a double wave generator 14 and a high AC voltage generator 15. Light generated by spark discharge is made incident on the PROM element 16 through a shutter 17, an image forming lens system 18 and a half mirror 19. The image generated only by the spark discharge is recorded on the PROM element 16. Read-out light is made incident on the PROM element 16 through a laser light source 20, a polarizer 27, a light shutter for reproduced light 21, a beam expander 25 and the half mirror 19, and emitted read-out light is reproduced as the optical image after the light passes through an analyzer 22, and the optical image is displayed on a monitor 24 through a TV camera 23.
