| Abstract: | Based on the electromagnetic theory, thermal energy principle and electron princi- ple of laser exciting ultrasonic is deduced. Optical testing method of laser-generated ultrasonic signal is studied. The result indicates that laser excite ultrasonic can produce narrow pulse repeat, it possesses higher kite resolving power in time and space, laser excite ultrasonic applies to nondestructive testing of material. |
| Keywords: | laser ultrasonic nondestructive testing laser-induced ultrasonic |
