Abstract
The study is based on a premise that if the polarization information from the reflected radiation is extracted by an imaging polarimeter, it is possible to reveal details about the surface that are not obtainable by other imaging techniques. A polarimetric analysis system is expressed mathematically, and the resulting mathematical notation taking into account the effects caused by rotation of the various optical elements is derived. A basic system design consisting of an optical, sensor, polarimeter control, and image processing subsystems is presented. Computer analysis of the optical components is used for the optimization of the complete optical system. By including a filter, quarter-wave plate, and dichroic polarizer in the analysis, prediction of the focusing requirements of the system is made possible. Results of laboratory-based experiments are assessed.
