His experience is primarily in the area of the design, analysis, and tolerancing of optical systems. Some of his fabricated designs include refractive relay and projection lenses for CRT, laser, and light valve sources, anamorphic laser scanning lenses, dome projection lenses exceeding 180° field of view, visible and IR band lenses for detector testing, variable-magnification beam expanders for IR and visible wavelength lasers, helmet-mounted night vision optics, copy lenses for graphic arts, astronomical telescope optics, null lenses, high-speed optical disk objectives and laser diode collimators, a star tracker, catadioptric grating spectrometer, and head-up display lens. |
| Having been involved in numerous projects at ORA requiring all-reflective configurations, he has developed a variety of obscured and unobscured reflective designs for potential use in x-ray lithography, sensor testing, and ultraviolet through IR band imaging. He has developed and documented user-defined constraint techniques to aid the optimization of such systems while controlling their packaging constraints, and has received two patents in the field of unobscured reflective optics. His laboratory experience in this area includes interferogram analysis of multi-mirror systems in support of compensator adjustment for alignment. |
