Abstract
An optical sensing system includes a transmitter configured to transmit a free-space optical signal toward a target, and a receiver configured to receive a reflected free-space optical target signal from the target. The receiver includes a phase sensitive amplifier (PSA), a homodyne detector coupled downstream from the PSA, and a controller configured to adjust a phase of the PSA based upon the homodyne detector.
