Abstract :
Laser-based ultrasound offers the capability for performing ultrasonic inspections in remote and limited access areas by coupling the lasers through optical fibers. The key factors needed for successfully implementing a fiber-based remote and limited access LBU system will be described. We report on design tradeoffs and preliminary experiments that have been conducted with a fiber-based inspection system.
