Optical Radar Transceiver Control Apparatus.

Abstract

The apparatus is part of an optical radar set and comprises a high powered C02 pulsed transmitter laser which is injection controlled to operate at a fixed frequency offset from a lower powered C02 local oscillator laser. A portion of the output of the local oscillator laser is applied to an acousto-optic Bragg cell, together with an RF signal equal to the desired intermediate frequency of the radar set. The upshifted first order output of the Bragg cell is injected into the transmitter laser for stabilization purposes. This results in a stable intermediate frequency for the optical radar set.
