Abstract
A combined active and passive imaging system comprises a radiation sources configured to output radiation beams towards a detector and an object in a scene. The system further comprises the detector configured to record superposition of instances of intensity patterns of interferences between at least a portion of the radiation beams and at least a portion of return radiations from the object. The detector may further be configured to record ambient light reflected from the scene. The detector may output a first signal with the recorded ambient light reflected from the scene and a second signal with the recorded superposition. The system further comprises a processor communicatively coupled to the detector and the radiation source unit. The processor may receive the first signal and the second signal and select the object in the scene.
