Zero position's variation is one of the important indicators to measure the stability of the optical sight. And the repeated installation's error cannot be ignored for the high-precision optical sight. So we design a device that can automatically eliminate the repeated installation's error. It consists of an automatic fitting device with a spectroscope and an autocollimator. A micro-motion fine-tuned closed-loop feedback system is formed with a pressure sensor and a piezoelectric ceramic micro-displacement device to achieve real-time adjustment of the space posture of the spectroscope. The experimental verification shows that the accuracy of system can achieve 1.5² within the 2° measurement range. Using this system, the precision of the zero position's variation of the high-precision optical sight is up to 2², which is sufficient to meet the measurement requirements for the zero position's variation of the high-precision optical sight.
