Paper Abstract

In response to the accuracy of most autocollimator measurement is not high, and limited to one-dimensional static measurement., we designed a kind of high-precision photoelectric self-collimation measurement system which based on position sensitive detector(PSD). The system uses a return-type optical path to reduce equipment size, and the use of neural network based on the PSD for the non-linear correction. When the distance is 10m, it can achieve the measurement range ± 4', full-range measurement error of less than 0.1", measurement resolution of less than 0.01" and other technical indicators.
