Laser shock peening system with time-of-flight monitoring

摘要

A system (10) and method for monitoring a laser shock peening process includes a sensor (14) connected to a controller (16). The controller (16) includes an input (36, 40) and a processor (38). The input (36, 40) is connected to the sensor (14) to receive a signal indicative of a laser shock event at a workpiece (20). The processor (38) is connected to the input (36, 40) and is configured to determine a time-of-flight (48) of residual energy associated with the laser shock event from the workpiece (20) to the sensor (14) and determine peen quality from the time-of-flight of the residual energy.
