Discussion of optical depolarizer in the remote sensor

The application and design principle of optical depolarizer in the remote sensor is discussed. In this paper, the improved Lyot depolarizer is designed for Ocean Color Scanner. The parameters of depolarizer, such as the rest polarization, beam deflection and angle blur, are analyzed. According to the use of remote sensing system, the testing methods are suggested. The result from the test is the optical depolarizer is excellent for Ocean Color Scanner.
