In order to realize the error detection of high precision optical encoder, an error detection method of optical encoder based on optical continuous closed loop (OCCL) was proposed, by the principle of small angle measurement of photoelectric autocollimator and single reflector. Firstly, the configuration of the OCCL error detection platform for optical encoder is designed. Then, the error detection principle of the OCCL optical encoder is analyzed. Finally, the OCCL photoelectric encoder error detection system is established, and the calibration auto-collimator and the regular 23-hedral polyhedron are used to calibrate the accuracy of the detection system. The experimental results show that the new photoelectric encoder error detection platform is frequent, convenient, stable and reliable, and the accuracy of the detection platform can reach 1.64” in the rated working speed range, which can meet the requirements of high precision (2”) and 360° full circle continuous error detection for the encoder.
