Abstract:
1. A combined active and passive imaging system comprising: a first coherent radiation source comprising: a second coherent radiation source comprising: the first detector configured to simultaneously record a first instance of a first superposition of a first intensity pattern of a first interference between at least a portion of the first radiation beam and at least a portion of the return radiation from the object, and a second intensity pattern of a second interference between at least a portion of the second radiation beam and at least a portion of the return radiation from the object, wherein the first detector is further configured to record ambient light reflected from the first scene, and wherein the first detector is further configured to output a first signal with the recorded ambient light reflected from the first scene and a second signal with the recorded first superposition; and a processor communicatively coupled to the first detector, the first coherent radiation source, and the second coherent radiation source, wherein the processor is configured to receive the first signal and the second signal, and wherein the processor is further configured to select the object in the first scene.
