abstract = "This paper presents the design of a real-time and high-precision photoelectric autocollimator. Firstly, a far exit pupil distance and no vignetting optical system is proposed. Compared with the conventional optical system of autocollimator, it solves the problem of ray cutting which results in the detection accuracy changed with the distance of target lens. Besiedes, it eliminates the influence of stray light. Then, the design of photoelectric detection system is discussed. It uses the specific multi-frame superposition denoising algorithm based on high speed CMOS camera which solves the conflict of improvement of accuracy and time-consuming of the algorithm. Finally, test results of the instrument are given. The measurement repeatability of the autocollimator can reach up to 0.01″ with the measurement range of 1200″ and the single measurement time is less than 17ms.",
