Paper Abstract

Modern infrared (IR) imaging systems are sensitive enough to detect weak targets, but background clutter makes the detection difficult. The introduction of an IR polarizer into thermal imaging systems is one of the techniques to improve this low target-to-clutter ratio. The use of polarized IR energy helps to detect man-made objects in complex natural backgrounds. Over the past 4 years, we have investigated the polarization properties of thermal IR radiation (8 - 12 micrometers ). In the course of our work, we have built an infrared imaging polarimeter and participated in field and laboratory experiments. This paper summarizes the results of our work. It includes a brief theoretical background, description of the equipment, and a comparison of our empirical findings with a theoretical model and with results of other researchers.
