The study of M/sub A/ active optics control system used for LAMOST

The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) as one big-science project in the Ninth Five-Year Plan period (1996-2000) is a meridian reflecting Schmidt telescope. The MA active optics system is the key technique and the difficult point of LAMOST. In this paper, a distributed control system based on CANBUS is presented to be used for controlling the MA,and the framework and working of this distributed control system is discussed.
