Research on High-precision Can Reject the Repetitive Positioning Error of Zero Position Detection Method

According to inspection technique status of high precision small arms sight-telescopes, a method of rejecting the repetitive positioning error and implementing the high-precision detection of sight-telescopes zero position variation was studied. The simulation of infinite far target and the measurement of sight-telescopes repetitive positioning error were implemented by using photoelectric autocollimator;CCD camera instead of human eyes was used in viewer-sight scenery of sight-telescopes and detection for aiming point position changes. This principle formula was derived based on photoelectric self-collimating installed error reject method modeling;the measurement errors of sight-telescopes zero po-sition variation were analyzed;the feasibility of this method was verified by experiment. The result showed that the de-tection of high-precision zero position variation of 0.01 mil can be implemented by this method and high precision measurement of this sight-telescopes zero position variation can be guaranteed.
