System for passive and optical-mechanic scanning of a visual field

摘要

Disclosed is a system for passive and active optical- mechanical scanning of a visual field. A passive channel uses a thermal imaging system scanning in two coordinates and an active channel uses a laser beam which is deflected in two coordinates. During scanning in the active and passive channel specific phase relations are maintained. The system according to the invention represents a device for passive and active scanning of a visual field which works with low transmitting power and in which the mutual interference of active and passive channels is prevented. The system can be used particularly for steering (active channel) of flying bodies or for the control of machines or devices over certain distances.
