偏振干涉法用于偏振器消光比的测量

Measurement of Extinction Ratio of Polarizer Using Interference Method of Polarization

提出一种偏振器消光比测量的新方法。由于采用了高消光比偏振分光系统和相干探测技术，使得消光比的测量方便和准确。

in this thesis,a new measurement method of extinction ratio of polarizer--interference of polarization light--has been described. By the use of polarization beam splitting systemwith high extinction radio and coherent detecting technology,the measurement of extinction radiobecome easier and more accurate.
