Mirror structure

摘要

A mirror structure is provided in which at least a portion of a wavefront sensor is integrated with a mirror. In particular, a mirror structure is provided in which a Hartmann mask or a microlensarray of a Shack-Hartmann wavefront sensor is integrated with a mirror to provide a very compact wavefront detector/corrector in a single device. Such a mirror structure may be used with a tip-tilt stage in a laser cavity to provide much simplified adaptive optics in the cavity. Furthermore, a Hartmann Mask may be integrated with self deforming mirror comprising an active PZT layer bonded to a passive mirror substrate, wherein the Hartmann Mask comprises an array of apertures formed through the active PZT layer.
