Abstract

According to the definition of extinction ratio, the paper analyzed two test methods of polarizer extinction ratio, and proved that these two kinds of systematic errors caused by the approximate formula are equal under the same condition. Generally, the extinction ratio of the polarizers to be measured is 2 orders of magnitude lower than the known polarizers, and the system error can be controlled within 1%.
