Abstract

A Polarization Filter Array (PFA) camera is an imaging device capable of analyzing the polarization state of light in a snapshot way. These cameras exhibit spatial variations, i.e. nonuniformity, in their response due to optical imperfections introduced during the nanofabrication process. Calibration is done by computational imaging algorithms to correct the data for radiometric and polarimetric errors. In this paper, we review existing calibration procedures, and show a practical implementation result of one of these methods applied to a commercially available PFA camera.
