Solid State Compact and Rugged Personal Environmental Recording System Employing Inertial Sensors and Electromyographic Monitoring

Innovative approaches are required to make the interferometric testing of large aspheric, and/or non-axisymmetric surfaces both flexible and cost effective. QED proposes to develop a scanning, off-axis, subaperture system aimed at extending thecapabilities of interferometric testing to cover larger clear apertures (200mm), larger numerical apertures (0.5), and larger aspheric departures (>200 waves), with increased accuracy through calibration. This system represents a significant advance that,with further development, could offer general test capabilities for a wider range of conformal optics. Our system's success relies on the proposed innovations for efficient subaperture stitching, automatic system calibration, absolute measurements, andextended dynamic range through high-density interference fringe analysis. Fundamentally limiting challenges to aspheric metrology are addressed principally by automatic calibration to remove the errors associated with aberrations in both the imagingoptics and in the reference wave, as well as corrections for positioning errors and image distortion. Success in Phase I has provided the foundation for the Phase II tasks of developing a fully automated metrology system for more strongly aspheric optics.Our prospects for success in both developing and commercializing the final product are greatly enhanced by the fact that QED has entered into a co-development collaboration with a leading interferometer supplier.
