Abstract
A method of remotely sensing an object includes: collecting photons from the object; directing the photons down pathways, wherein photons in each of the pathways have a different polarization state; detecting photons in each of the pathways using at least one optical detector, wherein the photons in each of the polarization states produce a signal; receiving, with at least one processor in communication with the at least one optical detector, signals corresponding to the photons in the pathways; determining, with the at least one processor and for a segment of the signals, at least one of: an angle of linear polarization, a degree of polarization, and a degree of circular polarization; and generating a signal corresponding to a sequential output of the angle of linear polarization, degree of polarization, or the degree of circular polarization for each segment.
