Abstract

We report detection of space shuttle insulation foam defects by using a 0.2 THz Gunn diode oscillator as the light source, and a pyroelectric camera as the detector. The size and location of the defects are identified, and the feasibility of using this imaging system in quality inspection is discussed.
