ABSTRACT:
Two pyroelectric vidicons are adapted to alternately receive infrared ene radiated from an object by means of a rotating half circle mirror and fixed mirror arrangement. The alternations of the infrared energy received between the two vidicons are synchronized by means of a synchronization and drive circuit adapted to receive frame sync pulses from the camera circuitry. By this arrangement, information is received by the camera 100% of the time.
