Claim 10:
11. A method for computing a polarization signature, the method comprising:
receiving, by a processing system comprising one or more computers:
a first polarization image representing intensity of a first output beam after passing through a first polarizing filter at a first polarization angle;
a second polarization image representing intensity of a second output beam after passing through a second polarizing filter at a second polarization angle; and
a third polarization image representing intensity of a third output beam after passing through a third polarizing filter at a third polarization angle,
the first output beam, the second output beam, and the third output beam being split from an input beam by a beam splitter system; and

computing, by the processing system, pixel-level correspondences between the first polarization image, the second polarization image, and the third polarization image; and
computing an angle of linear polarization (AOLP) image and a degree of linear polarization (DOLP) image from the computed pixel-level correspondences between the first polarization image, the second polarization image, and the third polarization image.
