| 摘 要： | 由于部分偏振光与椭圆偏振光经旋转偏振片后，其光强发生相似的变化，所以难以区分.采用在椭圆偏振光路中加入2片1/4波片，在部分偏振光光路中加入1片1/4波片，从而加以区分.实验结果表明，部分偏振光的光强发生变化，但是没有出现消光现象，椭圆偏振光通过1/4波片变成浅偏振光，出现消光现象.

| Abstract: | Elliptically polarized light and partially polarized light show similar change in light intensity through a rotatable,so it is difficult to differentiate them.Application of two 1/4 wave plates in the path of elliptically ploarized light and one 1/4 wave plate in the path of partially polarized light is a way to distinguish them from each other.The experiment results showed that the intensity of partially polarized light changed with no extinction phenomenon，but the intensity of elliptically polarized light changed with the extinction phenomenon,and the elliptial polarized light changed into shallow polarized light through 1/4 wave plate. |
