Diffractive wavefront control has been demonstrated as a viable technique for high-dynamic-range laser wavefront control. Unfortunately, most conventional programmable diffractive elements, like liquid crystals and segmented mirror arrays, are damaged when illuminated with high-power laser light. The proposed work would investigate approaches for scaling membrane deformable mirrors to provide high-energy laser wavefront control with a large number of actuators.
Benefits: Success in developing this technology will provide the foundation to develop and market simpler, cheaper deformable mirrors for a variety of military and commercial applications. Government agencies that could utilize this technology include not only the DOD programs, but also NASA, the new Department of Homeland Security, and the NRO. Commercial applications in the fields of medical instruments, astronomy, photography, and optical equipment can also be expected.
