Abstract
An acousto-optic damage detector and locator uses acoustic energy propagated through a structure to modulate light transmitted through an optical fiber whereby the character of acoustic signals detected by the fiber varies according to the physical condition of the portion of the structure through which the pulses propagate to determine the existence, location and extent of faults within the structure.
