Computer generated holograms for aspheric optics testing
Paper presents the overview of the latest results of application of CGHs with more then 200 mm diameter and a minimum feature size of 0.5 micrometer for testing large aspheric surfaces with a Fizeau-type interferometer. Various experimental results are presented. Special attention was attended to the accuracy of adjusting the optical test system with the CGH and the problem of suppressing unwanted orders of diffraction. Designs of CGHs that can be used for optical alignment of complex optical systems are discussed.
