Adaptative Optics (AO) requires fast and precise wavefront control using deformable optical surface (DM) with a large number of actuators. Current commercial DM technologies are efficient but still suffer from limitations in their temporal bandwidth, dynamical range, size, number of actuators, fragility/fatigue, and non-linear effects that need to be overcome for future instruments. Moreover, these DMs have unperfect shape at rest and are costly. We aim to develop a new hybrid high-speed, lightweight, large and low-cost deformable-mirror technology.
