Paper Abstract

The issue of how best to distribute a large optical collecting area is revisited, including the added integration time required for a scene imaged by sparse-aperture configurations to be processed to equal that of a filled aperture, and also its influence on system architecture. The optical performance of three sparse-aperture configurations arising from a 1998 study is presented as a function of field angle and optimization criteria. Optimization of these three specific configurations shows ray FWHM and residual rms values small enough to assure excellent diffraction-limited imagery. Practical issues concerning fabrication, assembly, testing, and on-orbit phasing are identified.
