Photoelectric scanning is an effective method to improve the accuracy and sensitivity of the moiré method.In this paper, the structure and principle of the photoelectric scanning device are introduced in detail, and the method of using the displacement-light intensity theory to organize the fractional moiré is introduced. In this paper, the plane curved rod moire experiment as an example, the use of photoelectric scanning method to improve the measurement accuracy of 2-3 times the effect. Photoelectric scanning method is conducive to automation of experimental data processing. In this paper, a preliminary scheme of automatically processing data by photoelectric scanning and computer is proposed.
