ABSTRACT:
Automatic light control apparatus for a television camera system utilizing a gated image intensifier wherein a pair of laser diodes illuminate, respectively, a pair of avalanche photodiodes to apply switching voltages to the image intensifier. Low-level gating signals are utilized to activate the laser diodes. The laser diodes are gated on and off in complementary fashion whereby the image intensifier is turned on for pulse intervals inversely proportional to the brightness of the scene being televised.
