Abstract: A light detection and ranging (LIDAR) system is provided that includes a first optical source and a second optical source configured to emit respectively a first optical beam and a second optical beam that are nondegenerate and are chirped antiphase, lensing optics to direct the first and second optical beams toward a target, and collect a first return signal and a second return signal, and a first optical detector and a second optical detector configured to generate a first signal from the first return signal mixed with a first local oscillator and a second signal from the second return signal mixed with the second local oscillator.

Abstract: A light detection and ranging (LIDAR) system is provided that includes a first optical source and a second optical source configured to emit respectively a first optical beam and a second optical beam that are nondegenerate and are chirped antiphase and at least one tap configured to split each of the first optical beam and the second optical beam to generate a first local oscillator and a second local oscillator.

Abstract: A light detection and ranging system is provided that includes first and second optical beams that are nondegenerate and are chirped antiphase. Taps split the first and second optical beams into first and second high-power and low-power path optical beams. An optical frequency multiplexer combines the first and second high-power path optical beams into a single spatial mode optical beam, which lensing optics launches towards a target, and collects light incident upon the target into a return path. An optical frequency demultiplexer splits the return optical beam into first and second spatial mode optical beams, and mixers mix the first spatial mode optical beam and the first low-power path optical beam, and the second spatial mode optical beam and the second low-power path optical beam, to produce optical beams having first and second beat frequencies, which optical detectors detect and from which range and velocity of the target are determinable.
