Optical system of golay-3 synthetic aperture telescope of Fizeau style

In order to get high resolution, a optical system of golay-3 synthetic aperture telescope has been designed which adopt Fizeau multi-telescope frame. The angular magnification of sub-aperture is −4; the fill factor is 1/3. The configuration of light beam combiner is Cassegrain style added a lens. The total focal length is 6000mm; the field of view is 4′. Analyzed the imaging, the PSF have been improved remarkably, and the cut-off frequency of MTF is close to that of full aperture.
