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. Based on the theory of polarization aberration, the physical mechanism of polarization sensitivity is analyzed in this paper, and the relationship between polarization aberration and polarization sensitivity is revealed. Moreover, a method of calculating the polarization sensitivity based on the Muller matrix is proposed. The computational analysis model is established based on the polarization ray tracing algorithm. This method overcomes the shortcomings of the traditional single ray estimation method and definition method, and the accuracy and efficiency of calculation are greatly improved. Take a remote camera as an example, the polarization sensitivity is analyzed theoretically and experimental measurement. This method can be applied to the imaging optical system or the imaging spectrometer for polarization analysis.
