Paper Abstract

A division of aperture infrared Stokes imaging polarimeter (ISIP) with optimal linear polarization measurements is presented. The focal plane array of the ISIP is divided into four independent imaging channels by a lens array, which is turned into four independent polarimetric analyzing channels by placing four linear polarizers of different orientation angles in front of each channel and a wave plate in one of the channels. An optimization method for the four polarization analyzing channels is proposed to improve measurement accuracy. For a high priority to linear polarization measurement, instead of optimization for full states of polarization components, we optimize the ISIP first for linear polarization components and then for circular polarization component. We demonstrate that the orientation angles of the polarizers are set at 0°, 60°, 90° and 120°, respectively. The optimal retardance of the wave plate is 90° with the orientation angle of 0°.
