ABSTRACT:
An optical target detecting device and system are disclosed wherein a single lens system projects a beam of infra red radiation and a single lens system picks up target reflections of this single radiation. Additional lens systems including reflectors are disclosed along with the single lens system to increase the frequency of received optical radiation from extraneous sources. Frequency discriminating means eliminate the effects of the extraneous radiations while receiving the optical reflections from the desired target.
