10 December 1992 Study on quartz depolarizer
Author Affiliations +
In this article the emergence, development and present of depolarizer has been studied by me. Then I have studied the all quartz depolarizers existing presently. Such as single plate depolarizer, loyt depolarizer, single wedge depolarizer, right angle prism depolarizer, J.C. kremen double wedges depolarizer by theoretical analysis and experiment measurements. I have found when the polarization plane of the incident monochromatic light is unknown or frequently varies, the emergent light can not be depolarized completely by using all the existing depolarizers. According to this situation, I have invented a new type of double wedge depolarizer. I can depolarize the emergent light completely whether the polarization plane of the incident is known or frequently varies by using the new depolarizer. The polarization degree of the emergent light is below 1.0%, transmission ratio is above 90%.
