摘要：This paper investigates the optical analysis oftwo-axis scanning mirror and non-linearity correction of2D-PSD. Firstly, we consider the scan mirror about the pivotrange of the ratio and the scanning locus of swinging differentcoordinate systems. The formula of the scan trace of the scanmirror with different angle of pivot shaft are also obtained. Inthe actual measurement, the position sensitive detectors (PSD)are used to measure the scan mirror angle. In order to reducethe nonlinearity of scan trace, a bilateral linear interpolationmethod was given to reduce the nonlinear characteristic ofPSD.
