| Abstract: | For the purpose knowing the measuring accuracy of figure measuring system of optical lens based on image transforming manipulation, the figure measuring process of optical lens was described by mathematical expressions. Mathematical model of measuring accuracy is presented based on analyzing all sort of measuring errors during figure measuring process. The conclusion shows that measuring accuracy of the figure measuring method is very high. A sample figure measuring system is established. The results of some experiment data verify this conclusion. |
