Abstract：
 The invention includes T type optical path composed of four collimators installed on base, polarizer, beam splitter and Wollaston prism. First collimator, polarizer, beam splitter and second collimator setup in sequence constitute horizontal optical path. The vertical optical path includes beam splitter, Wollaston prism, third collimator and fourth collimator. Advantages are: simple structure, compact, small size, high stability, and easy to connect to optical fiber.
