Title: Highly Reflecting, Broadband Deformable Membrane Mirror for Wavefront Control Applications
Agency: NASA
Contract: NNX08CD54P
Award Amount: $99,999.00


This Phase I STTR project will develop a highly reflecting, broadband, radiation resistant, low-stress and lightweight, membrane integrated into an electrostatically actuated microelectromechanical systems (MEMS) device for wavefront control applications in space telescopes. The underlying technology builds on nanomaterial coatings and electro-optical modeling competency of the company. InnoSense LLC (ISL) will collaborate with Dr. Harold Kahn, Research Associate Professor, Department of Materials Science and Engineering at Case Western Reserve University, to integrate the low-cost, flexible nanocomposite membrane mirror into a MEMS device. The Phase I project would demonstrate: (a) a membrane mirror capable of high broadband reflectivity; (b) deflections > 20-30 micron; and (c) large temporal bandwidth at frequency > 1 KHz. The focus of Phase II will be optimization of the reflecting membrane, refinements to the design of the deformable membrane mirror (DMM) device, accompanied by extensive evaluation of prototype DMMs for their ability to correct for large wavefront aberrations at high frequencies to mitigate the effects of atmospheric turbulence, and enable high fidelity imaging capability. To ensure success of this project, ISL has assembled a technical team with a cumulative 70 person-years of experience in nanomaterials coatings, MEMS, mechanical and electro-optical modeling.
