Polarization analysis and control of a coastal zone imaging optics

Abstract

The polarization characteristic of ocean or atmospheric optical sensor is one of the important factors affecting the accuracy of radiation measurement and quantitative inversion. According to polarization ray tracing algorithm, a calculating model of the polarization sensitivity based on the Muller pupil is proposed. A complete coastal zone remote sensor with low polarization sensitivity is designed, optimized and controlled, by the cooperative design of optical configuration compensating and coating. The result shows that the linear polarization sensitivity is less than 2.5% at B1, and below 1.5% for other four bands respectively.
