Paper Abstract

Building on the technology developed to make deformable secondary mirrors for large telescopes, we show that a new breed of tip-tilt and low order deformable mirrors can be designed to satisfy the need of a large number of traditional astronomical AO systems that rely on a high order piezo deformable mirror compounded with a tip-tilt mirror to compensate for the large image motion present in the atmosphere. Using a new paradigm, we are developing a compact 50mm deformable mirror which benefits from a large computer power used to implement powerful control algorithms that allow speeding up the mirror response. Freed from the space and geometrical constraints that deformable secondary mirrors must respect, our mirror also displays elegant simplicity and compactness.
