摘要
An optical system misalignment solution-based method for evaluating the stability of an optical-mechanical structure. In the method, a system misalignment is solved according to a wave surface deviation of an optical system at an initial time point and a time point to be evaluated; a corresponding compensator is adjusted according to the system misalignment; a wave surface deviation of the adjusted system and the system at the initial time point is used as a criterion of stability evaluation, and the solved misalignment shows long-term instability of the optical-mechanical structure within the time period. The method is suitable for real-time evaluation of the long-term stability of the optical system with a complex optical-mechanical structure, and solves the problem that a conventional stability evaluation method is limited by spatial positions.
