| description | The invention discloses a method for testing the polarization degree of light scrambled by a light scrambler, and belongs to the technical field of optical measurement. In the prior art, a polarization state analyzer is used, the polarization degree of light scrambled by a light scrambler is approximately obtained through a polarization degree formula, and the method needs expensive instruments and is complex in system. The method of the invention comprises the following steps: sequentially connecting a polarization-maintaining light source, a polarization controller, a to-be-measured opticalscrambler, an analyzer and an optical power meter by using a single-mode optical fiber jumper; generating complete polarized light with a stable polarization state by the polarization-maintaining light source; adjusting the polarization controller by using an upper computer to enable the polarization state of light output by the polarization controller to be S1; adjusting the average time of the testing process of the opt |
