ABSTRACT:
A system and method for monitoring a laser shock peening process includes a sensor connected to a controller. The controller includes an input and a processor. The input is connected to the sensor to receive a signal indicative of a laser shock event at a workpiece. The processor is connected to the input and is configured to determine a time-of-flight of residual energy associated with the laser shock event from the workpiece to the sensor and determine peen quality from the time-of-flight of the residual energy.
