| Abstract: | In this paper, the principle of phase retrieval method with hardware and software realization is introduced. An experiment platform has been built including CCD translation stage and GS algorithm software. An experiment on a ball mirror of 500mm aperture has been carried out under the environment of on sit processing. The testing result showed high consistency with interferometer, can satisfied the requirement of polishing process. |
