Photoelectric encoder is a representative angle measuring device. In order to ensure the angle measuring accuracy in harsh working environments, key technology of signal processing for photoelectric encoder was illustrated. Taking the quality of Moire fringe photoelectric signal into account, the importance of photoelectric signal compensation for the improvement of angle measuring accuracy was revealed. On optical and electrical aspects, domestic and international present research situation of adaptive compensation technology for photoelectric encoder signal was elaborated. And typical compensation processing technology was analyzed. The demand for real-time signal compensation processing technology was revealed. Finally, in view of research progress of domestic and international photoelectric encoder, the future development trend of photoelectric encoder was briefly pointed out.
