Laser and Acoustic Excitation Safety

In the course of their employment, nondestructive test personnel may work near or with lasers. Lasers are used to generate and detect ultrasonic waves. Lasers are used in optical methods of nondestructive testing, particularly holography and shearography, as well as for precise measurement of displacement in a wide variety of strain monitoring for structures including critical infrastructure such as road embankments. More often than for inspection, lasers are used for joining and machining operations, including precise etching and cutting. Even inspectors who never use a laser are likely to work around them one day.
