Computer Generated Holographic Optics.
Abstract
The goal of this research was to theoretically and experimentally investigate the use of computer-generated holograms in the design and fabrication of holographic optical elements (holographic lenses or diffraction optics). Conventional design of holographic lenses had previously been limited to spherical recording beams, and more recently to recording beams formed by conventional optical systems. The utilization of computer-generated holograms in the recording beams allows a completely arbitrary specification of the recording wavefronts in the hologram plane, making possible a hologram lens of higher performance (lower aberrations) than previously possible. We refer to an interferometrically recorded hologram lens having a computer-generated hologram in a recording beam as a computer-originated holographic lens. We studied the basic limitations of computer-generated holograms, and integrated the analysis of computer-generated holograms and computer-originated holographic optical elements into ERIM's holographic optical analysis and design (HOAD) ray-tracing computer program. In addition, we designed, fabricated, and tested an optical system using a computer-generated hologram and a computer-originated holographic lens. (Author)
