Paper Abstract

A division of aperture medium wave 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. The experiments are performed for detecting camouflaged targets by using the optimized ISIP, which demonstrate that the polarimetric images are effective in detecting camouflaged targets form natural background and improving the signal to noise ratio of target images.
