| Abstract: | This paper introduces the principles of the formation of ultrasound grating. Regarding the difficulty in measuring sound velocity by using this phenomenon, it also discusses supporting measuring methods about the velocity of ultrasonic wave by ministrant equipment of testing the wave length made by the wave measurement principle of Miehelson interfcrometer. Therefore, diffraction pattern changes can be more clearly observed, and the measurement accuracy is improved. In addition, it provides experimental methods and results. |
