Abstract

The use of polarization as the principal parameter in target recognition and clutter reduction typically requires numerous field measurements with linear and circular polarizers in order to obtain a complete set of polarimetric images for a given target. We have developed a method which reduces the number of necessary field measurements to characterize the polarization state of a given scene. In polarimetric analysis with a single linear polarizer inserted in the light sensing path, it is found that three polarimetric images are sufficient to characterize the observed light field. These images are taken with the polarizer oriented at two mutually orthogonal directions and their bisecting direction respectively. These three polarimetric images form a basis set which allows the scene at any arbitrary polarization angle to be reconstructed. A synthetic polarimetric image data base can be easily realized with only these three images rather than the huge storage and retrieval requirements for a true measured data base. The coherency matrix of a quasi-monochromatic light wave together with Stokes vector and Mueller matrix are used to deduce the minimum required measurements in constructing a synthetic data base. Examples of measured and derived images will be compared and discussed.
