Abstract

Micro-polarizer array (MPA) imaging technology has special advantage in equipment volume, weight, real-time imaging etc. All these advantages expand the application of polarization imaging. But little research has been done on how to design MPA parameters, and how to arrange MPA cells, and how to calculate polarization parameters from acquired images. In order to solve this problem, the study of micro-polarizer array (MPA) imaging was carried out in this paper, the grating diffraction and equivalent medium theory were utilized in the design of the relevant parameters for MPA, and a joint coding and decoding design method in frequency domain for MPA was also put forward. The simulation results reveal that the choice of the design method for joint coding and decoding of MPA will have a significant impact on the acquisition performance of polarization information.
