Paper Abstract

In order to solve the evaluation problem of optical system under partially polarized light conditions caused by single ray tracing method, a full-field and full-pupil ray tracing method based on Stokes is proposed. The analytical relationship among the degrees of polarization (DOP) of the incident ray, the angle of the ray and the DOP of the emitting light is analyzed. The analysis results show that when the difference value between the incident angle and the refracted angle is less than 5.7°, the influence of the system on the DOP of the light can be reduced effectively. According to the space target polarization imaging requirements, a polarization imaging optical system with micro-polarizer array detector is designed. The resolution is 0.5m at the distance of 500km. Dynamic data exchange (DDE) is used to trace the full-field and full-pupil rays for the optimized optical system. Due to the DOP of any field of view can be calibrated, the polarization detecting accuracy of the optical system is improved. Therefore, the target can be recognized by matching the DOP of the incident ray and the DOP of any field of view.
