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