Abstract

The Canada-France-Hawaii Telescope has undertaken the development of an Adaptive Optic bonette for general use at its telescope. There will be separate mirrors for tip-tilt and for higher order corrections. A 19 element curvature wavefront sensor will be used with a bimorph (19 electrodes) deformable mirror. Modal control will be used in order to optimize the number of modes corrected according to the atmospheric turbulence coherence time and brightness of the reference source. The optical design minimizes the number of reflections by using off-axis mirrors. It is planned that various instruments such as CCD cameras, IR cameras and integral field Spectrographs (TIGER type) will be used. At this point phase A design studies have been completed and fabrication has started.
