Reading Correction of Two-dimensional Electric Rotating-mirror Based on Optical Transmission Matrix

摘要

Aiming at correcting two-dimensional rotating-mirror's reading in optical scanning or rotation, in this paper, a reading correction method based on optical transmission matrix is proposed. A mathematical model based on the measurement principle of two-dimensional turntable in the system is applied to get pitching angle and azimuth angle of the emergent ray. By using the high-precision theodolite to proofread the direction of the adjusted emergent ray, the correctness of the model is verified. The experimental comparison and analysis indicate that this method without increasing the accuracy of processing and installing can revise the reading of two-dimensional rotating-mirror. It is proved that the precision can be 4".
