Abstract
Vibration waveforms in materials appear in video as a minuscule fluctuation in the light scattered into the camera. By inferring from processed video how vibrational energy propagates through an article to be inspected, we may detect local material anomalies. We report progress in developing measurement protocols and technologies to perform standoff nondestructive inspection of materials for defects using video image processing. In particular we show promising results from a protocol that conforms to relatively inexpensive hardware.
