Abstract
We propose to explore the feasibility of a novel concept for a low-cost, lightweight, rugged integrated adaptive-optics wavefront corrector system. These features are achieved by integrating a deformable mirror array onto the front surface of a custom VLSI wavefront processor chip and a wavefront sensor onto the back surface. The chosed processor chip structure is integral to the wavefront correction algorithm, and the proposed concept offers the potential for extremely high actuator density. We will conduct a feasibility analysis to determine those commercial applications that may have significant markets for our compact, low-cost, high-performance, and then design and model the novel wavefront corrector (custom VLSI and special membrane mirror with piston-only correction). These devices will be tested separately to verify the desired performance characteristics. The Phase II will scale-up the actuator density to a 256 x 256 array and demonstrate high-resolution wavefront correction with a prototype system optimized for application in military seekers, FLIRS, and commercial imaging systemssuch as amateur telescopes. The VLSI-membrane mirror wavefront corrector will offer isolated actuators, hundreds of nanosecond response time, and at least 16 pi radians of phase correction at visible wavelengths using achromatic illumination.
