| Abstract: | Annular subaperture test method has been developed for low cost and flexible measurement of large, fast aspheric surfaces without any special elements. The measurement principle of this method is simply introduced. The two representative algorithms based on discrete phase values and Zernike polynomials are numerically analyzed, and the result of primary experiment is provided. The results show that the method is feasible and provided that the potential for testing large aspheric mirror. According to the integrative analysis of the above research results, the experimental scheme of testing meter class aspheric mirror with annular subaperture method is presented． |
