Author Affiliations +
Several techniques for testing aspheric surfaces are presented, with the emphasis on interferometry. Techniques for setting up configurations to produce easily understandable null interferograms are described. Attention is also given to techniques that improve the readability of the more complicated interferograms produced when an asphere is tested at its center of curvature.
