摘　　要：本文通过坐标变换导出了一种二维光束扫描系统的光束表达式．利用该表达式对扫描振镜的非线性畸变作了讨论．指出，这种畸变只在X镜的扫描方向上发生，而畸变的程度与Y镜的偏转角有关．In this paper the optical beam formulae of the two--dimensional optical scanning system isdeveloped by coordinate transformation. By the formulae, the non -- linear distortion of scanningvibrating mirrors is discussed. It is concluded that the distortion is produced in the scanning directionof X mirror,but the degree of distortion is related to deflection angle of Y mirror.
