Abstract

The main feature of a large ten-meters telescope is application of 84 segment primary mirrors which are united in one reflecting system. This decision makes the problem of the primary mirror designing easier yet brings another task: the designing of every mirror segment high precision (nanometer accuracy) drive, which provides perfect coincidence of segment mirrors constantly. There are suggested two variants of the drive construction based on magnetic rheology liquid. This drive provides nanometer precision and millisecond quick action.
