Abstract
A hybrid ultrasonic technique was developed for the inspection of rails. Acoustic signals are generated with an IR pulse laser and detected with a micromachined capacitive air-coupled transducer. The experiments demonstrate the flexibility and capability of the Laser-Air Hybrid Ultrasonic Technique to detect critical cracks that are not easy, or impossible to detect, with current inspection techniques available to the railroad industry. The noncontact and remote nature of this technique renders it suitable for in-service applications.
