Abstract

Polarization imaging sensors using the division-of-focal-plane paradigm have recently emerged on the market. These sensors, due to their compact design, are ideal for field work. One of the major drawbacks in these sensors is the spatial variation of the optical response of individual pixels across the imaging array. These spatial variations are due to variations in the nanowires of the pixelated polarization filters. In this paper, we describe and compare two methods for calibrating a division of focal plane sensors. We present theoretical and experimental data for these calibration methods.
