Left-handed and right-handed rotation double function circular polarizer

Abstract

In order to gain circularly polarized light of left-handed and right-handed rotation by using a fixed device, a left-handed and right-handed rotation double function circular polarizer is designed with two ν/4 retarders and one polarizer, and its operating principle is analysed by matrix optical means. The result indicates that when the monochromatic light enters this circular polarizer in the positive direction and the negative direction, the emergent light should be circularly polarized light, of left-handed and right-handed rotation respectively. The testing system has been established to verify the above results.
