【Abstract】 The theory of optical holography and Fourier optics have been applied to the-analysis of diffraction images and interference fields in testing aspheric surfaces with Computer Generated Hologram (CGH). A new viewpoint which considered the null interference to be an indefinite range field in the testing set-up is proposed. The> experimental results support above conclusion.更多还原
