朱超逸, 陆炜鑫, 高红, 王玫 . 基于横向莫尔条纹的自准直测角方法[J]. 大学物理, 2020 , 39(05) : 74 -77 . DOI: 10.16854 /j.cnki.1000-0712.190264
principle，based on the lateral Moiré fringe of auto-collimation angle measurement method，is analyzed by using
the shading principle of Moiré fringe displacement amplification effect. On the basis of the method to build the
principle of the optical path，the Moiré fringe signal is stable and can satisfy the measurement requirements. On the
basis of the system，data processing steps are simplified and dynamic measurement is realized. The quantitative calibration
experiment results show that the system resolution up to 10″，applying this method to the autocollimator can
significantly improve the resolution.
