Abstract: The technology disclosed herein includes a system having a light source configured to generate a laser signal, an optical signal splitter circuit configured to split the laser signal into a first laser signal for transmission to a plurality of targets and a second laser signal, an optical signal scanner configured to transmit the first laser signal to the plurality of targets, two or more optical delay lines configured to receive the second laser signal, wherein each of the two or more optical delay lines adds a predetermined time delay to the second laser signal to generate a delayed second laser signal, and a detector configured to receive a reflected laser signal from the plurality of targets, wherein the reflected laser signal includes a reflection of the first laser signal from the plurality of targets, and the delayed second laser signal.
