Abstract
Star Test Polarimetry is a method of inferring polarization information in a single irradiance measurement from the shape of a point spread function [1]. We present the optical design of an image sampling polarimeter that utilizes a stress engineered optical element to image the polarization states of scattered light collected by a lens across a given field. In our scheme, an intermediate image is sampled by a pinhole array and a relay system projects the polarization dependent point spread functions to a CCD. In this way, we show polarization mapping of a sample using a single irradiance image.
