Laser shock peening plasma diagnostics sensors for real time process monitoring

A system for monitoring a laser shock event includes a detector (20,74,110) connected to a controller (14). The controller (14) includes an input configured to receive a signal from the detector (20,74,110) that is indicative of an emission (36,75,128) associated with a laser shock event at a workpi...

Zusammenfassung:	A system for monitoring a laser shock event includes a detector (20,74,110) connected to a controller (14). The controller (14) includes an input configured to receive a signal from the detector (20,74,110) that is indicative of an emission (36,75,128) associated with a laser shock event at a workpiece (26,56,120). A processor (16,76,140) is connected to the input and is configured to determine a cause of an unacceptable peen event from the signal associated with the emission (36,75,128).
