Abstract

In order to achieve real-time polarization imaging, in order to improve the accuracy of target recognition and quickness, and improve the image quality of polarization imaging, this paper puts forward a kind of based on liquid crystal phase variable retarders LCVR and liquid crystal tunable filter LCTF polarization imaging, through LCVR to obtain the fourth stokes parameter in order to achieve full stokes polarization imaging. Points is used after the focal plane method to analyze the image obtained by CCD, focal plane method for points in a super pixels, spacing between units, making different polarization states measurements do not match the sample point to improve and solve problems, to use frequency domain analysis method to improve the polaroid array arrangement, polaroid array has more advantages, effectively improve the measurement of the highest frequency, improve the image quality of polarization imaging.
