Abstract

Spectral imaging and polarimetric imaging appear new trend to merge into the spectropolarimetric imaging technique, which can detect the 2-D image, spectrum and polarization of the target. The new technique has wide potential applications in the optical detection techniques. The static imaging spectropolarimeter has quite a simple and compact configuration and no mechanically moving elements for polarization control or active elements. In addition, it has the throughput and multiplex advantages. The principle and the system model of the new technique are given. The theoretical formulas of the interference intensity and the modulation process of Stokes vector are also presented. The data collecting and spectropolarimetric parameter reconstructing processes are analyzed theoretically, and a whole process mathematical simulation for the system is introduced. The theory analysis and simulation results proved the feasibility of the system, which can detect the image, spectrum and polarization of the target simultaneously. This research provides theoretical and practical supports for the development of new optical remote sensors.
