A hologram CAD (computer-aided design) tool capable of designing holographic optical element (HOE) is described. We have been developing this tool which is specialized for holograms. An optimum HOE lens with high diffraction efficiency and diffraction limited imaging characteristics is designed with the tool by applying a computer generated hologram (CGH) which generates an aspherical wave. The imaging characteristics of the HOE lens are experimentally verified and desirable results are obtained.
