Abstract

The invention discloses a method for analyzing polarization characteristics of a coated optical lens based on a Mueller matrix, relates to the field of optical system analysis, and solves the problem that the polarization characteristics of an optical system cannot be calculated and improved in a design stage in the prior art. According to the method, Mueller matrix analysis models of different mirror surfaces and surface film systems of the whole optical system are sequentially established in the actual light propagation direction through forward derivation, by means of the research result of the method, the Mueller matrix representation form of the whole optical system can be obtained in a Mueller matrix multiplication mode, and the polarization characteristic of the whole optical system is analyzed; and the independent polarization influence can be researched by analyzing the Mueller matrix of each mirror surface and film system, and targeted improved design is carried out, so that the design and optimization of the optical system with large field of view, wide band and low polarization characteristic can be finally realized. The method has important theoretical significance and engineering value for high-precision design and quantitative application of the polarization spectrum remote sensing instrument.
