Abstract
One way to overcome the turbulence perturbations problem on ground based telescopes is to use adaptive optics. The main components of an adaptive optics system developed for several years at ONERA are reviewed here. The different structures of 21 actuators monolithic piezoelectric and electrostrictive deformable mirrors are described. The Hartmann-Shack wavefront sensing technique is presented. The wavefront reconstruction and the mirror control algorithms and processors are mentioned. An adaptive optics test bench associating these components is detailed. Some simulation results dealing with aberrations correction are given.
