Abstract

Computer-generated holograms are often used to test aspheric surfaces. This paper provides a parametric model for the CGH phase function using the exact geometric model. The phase function is then used to derive the sensitivity functions to alignment errors in testing. When using the CGH to test aspheric surface, it is important to separate the diffraction orders and only allow the desired order to pass the system. This paper also provides a recipe for determining the amount of carriers needed to eliminate the ghost images.
