A new laser ultrasonic approach for detection of small surface-breaking defects is presented. Referred to as Scanning Laser Source (SLS), the technique includes a fiberized portable Q-switched YAG:Nd laser, which can be combined either with conventional PZT transducers or laser interferometers. For demonstration purposes, results are presented for detection of small EDM notches and fatigue cracks on flat and curved specimens and thin plates including real structure such as an aircraft turbine disk.
