| Abstract: | For testing aspheric surface more precisely, the authors present the computer generated hologram (CGH) used for testing aspheric surface, and analyze the optical path that is used for testing aspheric surface,deduing the position of CGH stripes for testing binary axially symmetric aspheric surface, and obtaining the CGH pattern equation. According to the research result, the authors simulate and analyze the optical testing path. The result of simulation shows the testing method of CGH compensating for diffraction can measure the aspheric surface with the higher precision than conventional method, and the RMS is less. |
