“…The MIT Adaptive Reconnaissance Golay3 Optical Satellite (ARGOS) demonstrated the practicality of a modular architecture for space-based optical systems for the first time with a FOV of 3-10 arcmins. In 2008, Wang et al presented a MMT prototype [10] in which the spherical primary mirror consisted of eight annular sub-mirrors and one central mirror.…”

A Golay3 multi-mirror telescope (MMT) system is designed in this paper. The fill factor of the Golay3 MMT is derived from the angular resolution of the telescope. An initial configuration is established according to the paraxial optical theory. A three-element aspheric corrector group is designed and placed in the converging light cone to enlarge the field of view (FOV) of the Golay3 MMT. The tolerance analysis for each surface of the Golay3 MMT is conducted using the Monte Carlo method. The design results show the FOV of the Golay3 MMT system can be increased to 1.5° with the insertion of a three-element aspheric corrector group. The results of the tolerance analysis indicate that most tolerances are loose, while some decenter tolerances relating with the aspheric surfaces are relatively tight, but still within an acceptable range.
