| Abstract: | A new technology developed since the middle 1970s, laser-ultrasonic testing system can complete nondestructive testing by the non-contact mode instantaneously, and combine with optics easily. The laser-ultrasonic nondestructive testing system is discussed, and the design of way of light, amplifier and demodulator is given. The error rate of the system is about 0.49% in the testing. |
