Abstract
This paper describes a method that uses pulsed laser light and coheren t light interferometry in a fiber-optic-based system for non-contact g eneration and detection of ultrasound Fiber-optic bundles are used to construct a rugged and versatile system to deliver geometrically condi tioned, high-energy laser pulses capable of generating ultrasonic sign als. In addition, an actively stabilized, multi-channel fiber-optic in terferometric system for detecting these signals is described.
