Abstract
We report on the detection of space shuttle foam insulation defects with a 0.2 THz Gunn diode oscillator as the illumination source. A pyroelectric camera, a Golay cell, and a silicon beam lead diode are used as detectors. The size and location of the defects are identified and the feasibility of using this imaging system in quality inspection is discussed.
