针对测绘图像几何精度对光学镜头畸变稳定的要求，仿真分析了一偏场使用的同轴三反光学系统镜头的畸变稳定性．从而论证该光学镜头用于测绘相机的可能性。将光学系统畸变误差源分解为加工误差、装调误差、工作温度变化引入的误差、以及调焦引入的误差4个主要部分，利用光学设计软件仿真分析了各误差源单独做用时对光学镜头畸变的影响情况，仿真结果表明在引入误差源的情况下，所分析的光学镜头的相对畸变不变．绝对畸变的最大变化范围小于2个像元尺寸，光学镜头的畸变稳定，有用于测绘相机的可能性。

Optical distortion affects the geometric quality of images directly. With focusing on the stability of optical distortion required by the geometric quality of the images,the paper discusses the feasibility of using coaxial three-mirror system in surveying and mapping, with simulating the stability of this camera lens.The error source of the camera lens' distortion is composed of four main parts: errors from manufacture, from assembly, work temperature changing and focusing.The paper simulates the influence of each error source, respectively, on the camera lens' distortion using the optical design software. The results demonstrate that the optical camera lens' relative distortion does not change, and the maximum changing range of absolute distortion is less than 2 pixels size.It means the distortion of this lens is steady and the lens can be used in surveying and mapping camera.
