Abstract
Ultrasonic surface examination, of interest in a variety of manufacturing and maintenance situations, is facilitated by a method which involves localized sensing of a surface wave by optical-fiber interferometry. The method is particularly applicable for examination of surfaces in confined spaces and wherever line-of-sight examination is difficult.
