摘要
根据激光扫描平移加旋转法的测量原理 ,推导出了非球面光学零件面形测量的数学模型 ;对一个非球面反射镜进行了实测并对测量结果进行插值运算 ,进而拟合出零件面形的曲线方程。
The mathematical model of the surface shape measurement of aspherical optical components is built up according to the laser scanning measurement principle by the translation & rotation method. An aspherical reflector is tested and testing data are processed by the interpolation calculation, then the curve equation of the component surface shape is fitted.
