Abstract

The Japan National Large Telescope `SUBARU' will be completed on the summit of Mauna Kea by the end of the century. One of the major characteristics new to the SUBARU telescope is the active support system for its large monolithic primary mirror, which has 261 points of computer-controlled actuators to maintain a precise mirror figure. This paper describes the control principle, design concepts, results of engineering experiments and numerical simulations of the active support system to ensure the high imaging performance of this system.
