Paper Abstract

One of the designs for the University of California's ten meter telescope project has the primary mirror composed of many hexagonal segments. A total of 54 mirror segments surround the 3.6m central mirror. Each segment is supported by 3 position actuators which provide tilt and focus control. The mirror figure is maintained by a non-optical technique using edge sensors to monitor relative mirror segment displacements. Details of the project goals and the critical design characteristics, including the behavior of the control system, and the proposed mirror components will be presented.
