Abstract :
Based on the auto-collimation theory, auto collimator is a highly-precise measuring equipment used for small-angle measurement. In this paper, we do some research on optical path, hardware design and data processing method. We focus on four methods to measure spot displacement and reduce indication error, which provide key technical support for developing photoelectric auto collimator with high accuracy.
