Abstract

Sandia National Laboratory has constructed several segmented Micro-Electro-Mechanical (MEM) deformable mirrors that are under investigation for their suitability in Adaptive Optics systems for the Naval Research Laboratory. These mirrors are constructed in a hexagonal array and have been constructed with flat surfaces, or with optical power allowing each mirror to bring its subaperture of light to a focus similar to a Shack-Hartman array.^1,2 Each mirror can use the tip, tilt and piston function to move the focused spots to the desired reference location, and the measurement of the applied voltage can be used directly to power a similar flat MEM deformable mirror. This paper reports on the suitability of this reflective wavefront sensor for closed-loop Adaptive Optics applications.
