ABSTRACT:
An optical transceiver is provided for transmitting a light pulse to a target and for receiving a reflected light pulse from the target. The transceiver includes a light source for transmitting a coherent light pulse which is reflected by the target along a first optical path as a reflected light pulse. The transceiver also includes a trigger signal generating circuit, coupled to the light source, for generating a trigger signal to indicate when the light pulse is transmitted. The transceiver further employs an attenuation device, responsive to the trigger signal and situated in the first optical path to intercept the reflected light pulse, for attenuating optical transmission through the first optical path inversely as a function of time from generation of the light pulse. In this manner, reflected light pulses reflected from targets close to the transceiver receive a greater amount of attenuation than reflected light pulses reflected from more distant targets.
