Abstract
A hand-held sound source for use in an infrared or thermal imaging system that detects sub-surface defects in a structure. The sound source includes a transducer that is positioned against the structure to emit a sound signal into the structure. The sound source further includes an adjustable spring that pushes the transducer against the structure with a predetermined amount of force so that the sound energy is effectively coupled into the structure. The sound source also includes three stabilizing legs that stabilize the transducer on the structure. The length of each leg can be adjustable relative to the length of the other legs so that the sound source can be used against irregular surfaces.
