| Abstract | When testing aspheric surface by computer generated hologram (CGH), there are some engineering problems in experiments. Within a lot of experiments, some unknown conditions appeared, and we analyzed two of them in detail and simulated them in Zemax. The unwanted diffraction orders maybe bring ghost image, and ring source is a simple method to eliminate it. The parallelism error of CGH substrate will bring a non-rotational symmetric error in test result, which is shown as coma. The size of the coma is related by parallelism error and the degree of the coma is related by the angle compared with the origin position. And a rotation method was presented to know the influence of parallelism error. After that, the projection distortion is expounded in detail and distortion calibration is successful to guide to enhance the precision of aspheric surface. These analysis results are very useful in practical engineering applications. © 2014 SPIE.; When testing aspheric surface by computer generated hologram (CGH), there are some engineering problems in experiments.
