Computer generated holograms for testing optical elements.
The application of computer generated holograms to the interferometric testing of aspheric optical elements has been investigated, and it has been shown that they provide a convenient and practical method of producing an aspheric reference wavefront.
متن کاملUse of Computer Generated Holograms for Testing Aspheric Optics
It has been more than 36 years since Lohmann and Paris first described computer generated holograms (CGHs) [1] and CGHs have been used to test aspheric optical elements for more than 35 years [2]. Computer generated holograms are now widely used in the testing of aspheric optical elements and it is expected that their use in aspheric testing will greatly increase the next few years as the super...
متن کاملApplications of computer-generated holograms for interferometric measurement of large aspheric optics
Interferometric optical testing using computer-generated holograms (CGH’s) has proven to give highly accurate measurements of aspheric surfaces. New applications of CGH interferometry were developed to support the fabrication of the large, steep mirrors required by the next generation ground-based telescopes. A new test to certify null correctors was designed and implemented that uses small CGH...
متن کاملAlignment of Aspheric Optical Surfaces at Goddard Space Flight Center
Aspheric optical surfaces are becoming common in optical design. Fabrication efforts have improved, costs have reduced, and aspheres allow a designer to control more degrees of freedom using fewer surfaces. However, testing and alignment of aspheric surfaces is considerably more difficult than that of spherical surfaces. Testing requires expensive null lenses, and alignment requires numerous da...
متن کاملComputer- originated aspheric holographic optical elements
R. C. Fairchild* J. R. Fienup Environmental Research Institute of Michigan Radar and Optics Division P.O. Box 8618 Ann Arbor, Michigan 48107 Abstract. Holographic optical elements (HOEs) recorded with arbitrary aspheric wavefronts can now be analyzed with a holographic raytracing design program. The recording wavefronts are defined by analytical phase functions, for example, a two -dimensional ...
