Enhanced Fabrication Processes Development for High Actuator Count Deformable Mirrors, Phase II

There are a range of Government agencies and commercial markets that can take advantage of small stroke, high precision deformable mirrors. One application is for large, ground-based telescopes. By expanding the size of DM devices, these observatories will be able to shape more light using less hardware and less stages. Another application is long-range optical communications (lasercomm) systems for use in satellites, airborne vehicles and ground-based nodes requiring a secure, dependable connection. By creating larger, higher-precision arrays, not only is it possible to send more data at faster rates, but the distance between communication points can be extended due to enhanced error correction capabilities. A third application is for correction of quasi-static aberrations in primary optics in surveillance satellites due to manufacturing and thermal variations. Adding to its advantages of high-resolution capability, the light weight nature of BMC MEMS DM technology allows the payload to be reduced, a high priority of military satellite projects. A final application is that of laser pulse-shaping for material characterization and laser marking and machining. By creating larger arrays, control of the pulsed beams can be enhanced. In addition, the larger arrays will allow users to take advantage of larger beam diameters. This will allow scientists to better understand the composition of materials and allow manufacturers to make larger, more complex patterns. More »
