Paper Abstract

To make accurate imagin polarimetry measurements, it is imperative that the individual polarization images comprising a data set are spatially well registered. Both the Stokes Imaging Polarimeter at the University of Alabama in Huntsville and the Multispectral IR Stokes Imagining Polarimeter at Night Vision Laboratories use a rotating quarter-wave linear retarder followed by a fixed linear polarizer to measure Stokes vector images. The rotating retarder cause small amounts of image wander at the detector array. In this paper, we quantify the effects of this image wander on the calculated polarization parameters, and present data indicating the maximum acceptable image wander for typical scenes.
