Paper Abstract

Work covers design and optimization of optical systems for observation of transient events and moving targets in space, such as gamma-ray bursts, asteroids, comets, meteors, satellites, space debris etc. Several all-spherical full-aperture catadioptric designs with focal ratios within f/3-f/0.8 range optimized for large format CCD detectors are presented. Analyzed systems may be grouped in following families: a) Prime-focus/folded Newtonian systems: 1. Hamilton. 2. Sonnefeld. 3. Richter-Slevogt. b) Cassegrain systems: 1. Richter-Slevogt-Cassegrain. 2. Hamilton-Cassegrain. 3. Shenker. Principal results of the work are: 1. Development of several optical designs suitable for realization. 2. Comparison of systems of different design families with comparable performance. 3.. Atmospheric dispersion correction in large-aperture systems is analyzed, with proposal of compensation by motion of principal optical elements. 4. Historical survey and comparison of all-spherical full-aperture catadioptric systems is performed.
