Abstract

Abstract:

Optical polarization is a fundamental property of light, and it is therefore important to realize the high-fidelity transmission of optical polarization during the optical signal detection process. The optical beam splitter, as a conventional element to build the detection optical path /optical system, could significantly affect the polarization resolution capability of the entire detection system. Based on the theoretical analysis of optical transmission and reflection, polarization-preserving optical pathes with beam splitters can be designed to achieve both reflection and transmission polarization-preserving functions. Experimental data demonstrates that the optical path polarization fidelity is up to 95%. The polarization fidelity design scheme has characteristics including low cost, flexible adjustment and strong functionality, which provides further possibilities for the analysis and application of polarized light.

Key words: optical beam splitter, polarization information, optical path design
