Innovative Non-Contact Metrology Solutions for Large Optical Telescopes

NASA has unique non-contact precision metrology requirements for dimensionally inspecting the global position and orientation of large and highly-polished multi-segmented mirrors (in an as-installed configuration), such as those used on the James Webb Space Telescope. SURVICE Metrology has assembled a world-class team of metrologists and optical physicists to identify and develop innovative approaches to accurately inspect the positional accuracy of mirror segments using non-contact methods. In addition to our in-house staff of experts in metrology and optics, our team includes industry-recognized academic experts in metrology. What is needed is the ability to accurately measure the global position and orientation of mirror segments in an as-installed configuration using non-contact means from a safe distance to allow measurements to be made with minimal risk to the asset. SURVICE proposes to research and evaluate technologies under the Phase I effort with respect to feasibility, cost, and risk and downselect to the best candidate technology for development in a Phase II effort. SURVICE brings demonstrated metrology systems integration success that we will apply to the subject NASA challenge. We have multiple Phase II and Phase III success stories, have delivered custom metrology solutions.
