The need to characterize the dynamic response of deformable membrane mirrors is key to their efficient design and effective operation in future high bandwidth AO systems that can compensate in real-time for atmospheric turbulence. This proposal by Advanced Systems and Technologies, Inc. (AS&T) directly responds to the above NAVY needs with a unique and comprehensive testing station that employs an architecture supporting multiple modalities of optical metrology tailored specifically for DM devices and MEMS arrays. We describe a novel optical non-contact sensor fusion concept, the Multi-mode Interferometer for Evaluation of Dynamics in Adaptive-optic Systems (MIEDAS) that supports full dynamic and static characterization of deformable membrane mirrors. The unparalleled measurement capabilities incorporated in MIEDAS are uniquely suited to the new sensor technologies sought by the Navy for comprehensive DM characterization. This proposal lays out a work plan leading towards a Phase II prototype instrument that will provide a comprehensive test and evaluation platform for future Navy adaptive optic system developments. Benefits: Anticipated results from the Phase 1 effort include a proof of principal demonstration of the key components of the proposed instrument. This will entail characterization of deformable mirrors current being employed in adaptive-optic (AO) systems under various drive regimes. The outcome of the phase 1 effort will include independent verification of the key functions which will subsequently be integrated in the Phase II instrument prototype. Test results will aim to validate, under various drive regimes, the rapid measurement of DM membrane dynamics and visualization of the full-field static surface profile. The data from these tests will have established the utility of these functions individually and the basic viability of an instrument which permits correlation and data fusion from both measurements. The phase I effort will also furbish the basic designs which will support integration under a single system architecture to be developed under the Phase II effort. At the conclusion of the Phase I and II effort we will have completed development of a fieldable prototype MIEDAS interferometer. The instrument will be configured for portability and would have undergone site trials at NAVY test facilities. The commercialization potential arising directly from the proposed program includes potential customers involved directly in AO systems development and in DM and MEMS mirror manufacture, where MIEDAS is anticipated to find applications in manufacture and QA for device fabrication and more generally in development of DM control systems. More broadly, and because of its unique capabilities, MIEDAS is also anticipated to attract a wide range of interest from aerospace, marine, automotive and electronics manufacturers and commercial potential in areas where the data latency and restricted application of current technology renders their use inappropriate or impractical due to cost or time constraints. Potential markets also exist in the field of non-destructive testing and diagnostics. Return
