Abstract

Sculptured surfaces are increasingly used in design of modern compact optical systems. Null test with computergenerated hologram (CGH) using commercial interferometer is generally adopted to test sculptured surfaces. To quickly estimate the maximum line density of the null CGH and determine whether the sculptured surfaced can be null tested or not, the best fitting sphere of the sculptured surface under test is firstly calculated and the deviation between the sculptured surface and the best fitting sphere is calculated along the normal direction of the best fitting sphere. The direction of optical axis and the optical arrangement are optimized to obtain a null CGH with minimum line density. And now the deviation between the sculptured surface and the best fitting sphere is calculated along the normal direction of the sculptured sphere, which is in accordance with the practical design of the null CGH. Simulated results show the validity of the method of the best fitting sphere, the estimated and designed maximum line density of the null CGH is accordant. Finally CGHs for null test of two sculptured surfaces are designed.
