Paper Abstract

Natural light will be partially polarized or totally polarized after the reflection, scattering, absorption and refraction of the objects. When detecting the ocean from the satellite orbit, the remote sensing signal of water is mainly composed of three parts: radiation signals of atmosphere after photon scattering, the direct reflection of light when the sunlight reaches the surface of the water, and the light after scatting backward. The sunlight will be polarized when it passes the atmosphere. Also, the polarization state of the incident light will be changed when it passes in the water. For remote sensing cameras with quantitative detection application, it is necessary to suppress the polarization sensitivity of the system as far as possible. Through the layout of the optics, the film layer design, the design of the depolarizer, we can achieve low polarization sensitivity.
