Paper Abstract

We examine the low light level performance of a four channel polarimeter with a single photon counting sensor associated with each channel. Specifically, we investigate how the detection noise propagates through the polarimeter calibration matrix and affects the estimation of each intensity and mutual phase retardance. The variance is derived for each of these quantities as a function of polarimeter design, detector read-out noise, and average detected photon-electron count. Based on these variances, a metric is defined which can be used to optimize the design of the polarimeter. A specific polarimeter design is examined for high and low light levels. Performance curves are shown for various polarization input parameters and light levels.
