Abstract:
Custom polarimetric imaging systems have the main disadvantage of loss of time or spatial resolution. To overcome this disadvantage, a simultaneous polarimetric imaging technique based on division of chromatic coding realized by distributed color-polarizer filter is proposed. Taking the advantage of the aperture stop of the lens, utilizing the chromatic coding plate and multi-polarizer plate to construct three channels, simultaneous polarimetric imaging technique can be realized. This technique has the advantages of maintaining the time and space resolution of the imaging system, and eliminating the distortion and dislocation among images. This polarimetric imaging scheme may promote the development of polarimetric optical imaging technique.
