1. IntroductionThe photoelectric theodolite can measure the flight trajectory of the target in real-time and output real-time images while recording motion parameters and flight attitude, with accurate measurement results and low susceptibility to interference [1]. The primary mirror is an important component of the optical system of the theodolite. With the improvement in the observation resolution and the ability to gather light, the diameter of the mirror is getting larger and larger.
