Abstract.
The adaptive optics system for the Gemini South telescope, currently in the design phase, consists of several major subsystems. The largest subsystem, called the AO module, contains most of the optics and electronics and is mounted on one of the Cassegrain instrument ports. The initial system will be a conventional laser guide AO star system, but the plan is to eventually expand it to a multi-conjugate system. This paper describes the design challenges encountered and solutions that were derived for the AO module design. The approach to multi-conjugate version is illustrated, including optical, mechanical, electronic and controls issues.
