Abstract

The main feature of large ten-meter telescope is usage of 84 primary mirror segments which are united in one reflecting system. This decision makes easier the problem of the primary mirror manufacturing but brings another task -- drives designing for every mirror segment moving with high precision (nanometer accuracy) which provides perfect coincidence of mirror segments constantly. There are suggested two variants of the drive construction based on magnetic-rheology liquid. This drive provides nanometer precision and millisecond quickaction.
