DEVICES FOR DETECTING CONTAMINATION IN COATINGS

摘要

A device disclosed herein includes an optical detector that detects a specular reflection from a test article having a coating thereon. The device also includes a processor operatively coupled to the optical detector and configured to determine whether a contaminant is present at the coating based on the specular reflection and based on a calibration measurement determined from a test article having a known contaminant-free sample of the coating thereon. Another device disclosed herein includes an optical detector that detects a specular reflection from the test article having a coating thereon, with the specular reflection at an angle of less than 20° with respect to an axis normal to the test article. The device can further include a processor configured to determine whether contamination is present at the coating. Embodiments enable rapid, sensitive testing of epoxy and paint surfaces by minimally trained personnel.
