Paper Abstract

We present a novel method for integrating a wavefront sensor into a deformable mirror. This development should simplify the design of laser and electro-optic systems, and lead to smart mirrors which need no external control systems. In operation, a small fraction of the incident light is transmitted through the mirror coating and is sampled by a Hartmann Mask. Options include open loop, traditional closed loop or fully integrated operation whereby the wavefront sensor is used to provide direct feedback to the mirror actuators, enabling automatic alignment or phase conjugation.
