<p>The present invention relates to an apparatus for measuring the performance of removing disturbance of a high-speed steering mirror unit for a large aperture telescope. To be more specifically, the present invention relates to an apparatus for measuring the performance of removing disturbance of a high-speed steering mirror unit for a large aperture telescope, and to a large aperture telescope including the same which can remove influence on a fixating structure of a high-speed steering mirror unit by exciting components for measuring a tip-tilt driving signal in a large aperture telescope in order to generate disturbance, and can generate stable and accurate disturbance at low costs by simplifying a disturbance generator. The apparatus for measuring the performance of removing disturbance for a large aperture telescope includes an optical unit and a high-speed steering mirror unit capable of performing tip-tilt operation, and comprises: a tip-tilt driving signal measuring unit which is positioned to receive laser beams reflected from the high-speed steering mirror unit in order to measure the position of the laser beams; and a disturbance generating unit which excites the tip-tilt driving signal measuring unit vertically and horizontally in order to generate disturbance.</p> |
