Automated Window Inspection Device

The Automated Window Inspection Device (AWID) is a prototype apparatus for computer-controlled, noncontact inspection of windows, with reproducible positioning and electronic recording of data on the locations, sizes, and depths of flaws. The AWID was developed to accelerate and facilitate (1) postflight inspections of the windows on the space shuttle for damage by micrometeorites and (2) the recording, analysis, and retrieval of records of such inspections. The AWID could also be adapted to industrial inspection of window glass prior to cutting, and to inspection of windows on aircraft and land vehicles.
