Paper Abstract

One of the unique properties of deformable mirrors is their ability to be shaped. The as-assembled mirror figure can vary greatly, depending on the adjustment capability of the actuators used to shape it. Due to these variations, it is difficult to directly interpret progress during the mirror-polishing cycle when the interpretation is based only upon the metrology mterferometric readings. An in-process figure qualification procedure, which has been developed at Hughes Danbury Optical Systems, is described in this paper. By facilitating the real time monitoring of progress, the application of this procedure will accelerate the fabrication process of large deformable mirrors.
