Enhancements and Extensions to OSEE Contamination Inspection

  • C. S. Welch

Optically Stimulated Electron Emission (OSEE) is a non-contacting method found to be very sensitive to some contaminants on metal surfaces. It has been developed in the aerospace community as an inspection tool for verifying cleanliness of surfaces prior to bonding. Issues of stability and long term variability in commercially available OSEE instruments motivated an effort. at NASA Langley Research Center to improve the technology. This effort has gone through three stages: a science base study, development of an improved instrument for rocket motor inspection, and application of OSEE to a wider class of inspections.
