Abstract
A combined active and passive imaging system comprises a radiation source unit configured to output a radiation beam towards a detector and an object in a scene. The system further comprises the detector configured to record a first instance of an intensity pattern of an interference between at least a portion of the radiation beam and at least a portion of a return radiation 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 intensity pattern. 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.
