| Abstract: | On propagation characteristic of material surface, wave in laser ultrasonic, Fizeau fiber interferometer system which implements measure of SAW on YAG laser is researched. Based on interference principle in common laser path, the system eliminates many shortcomings in measurement means of other SAW. The system has many advantages such as low environment demand, simple configuration, easy adjustment, high frequency response and no contacted measurement. It adapts to laser ultrasonic measure. |
