Abstract

The application discloses a method for solving the misalignment of an astronomical telescope optical system based on a de-polarization coefficient, and the steps of the method comprise the following steps: 1) defining the misalignment of the telescope optical system, and selecting an image point on an image plane of the telescope optical system; 2) obtaining a Mueller matrix and a de-polarization coefficient at different image points of the telescope optical system; and 3) iteratively optimizing and solving the misalignment of the optical system by using a particle swarm optimization algorithm. The misalignment of the telescope optical system is solved by using the de-polarization coefficient of the telescope optical system through the iterative optimization mode by using the particle swarm optimization algorithm, the misalignment of the optical system can be quickly obtained, and thus the misalignment of the telescope optical element can be corrected, and the image quality is improved.
