基于分束器的光学偏振保真传输OA北大核心CSTPCD

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.
