Abstract

The application of a ray-tracing methodology to computer-generated hologram (CGH) as a special imaging lens is presented. The design is based on a relatively analytic solution involving the minimization of the mean-squared wavefront deviation of the output wavefront, i.e., by using the optimization techniques one might use a computer program to determine the hologram phase transfer function which exhibits minimum aberration of the output wavefront. We design the special imaging lens of the CGH to extend the field of view of the optical system. It demonstrates much lower aberrations than the comparable spherical image lens of the CGH. We use the ray-tracing equations to determine the image properties of the system. Some experimental results are shown.
