ABSTRACT:
A optical relay which includes a target plate which is made of an electrically insulating material and allows light to pass in a manner depending on the electric field parallel to the direction of propagation of this light, wherein a first side of this target plate is scanned by an electron beam produced by an electron gun, an anode in the form of a grid, a thin plate which is optically transparent and electrically conducting, an amplifier applying the video information of the video signal to the relay. The optical relay includes means by circuit elements which it is is capable of writing and erasing the target plate in the charge accumulation mode cooperating with a precursor eraser acting on a limited number q of scanning lines positioned beyond the line n to which the write operation relates. In order to transmit the picture in accordance with a television standard, a de-interlacing arrangement is used.
