Abstract :
The precise quantitative study of two optical beam diffraction by SAW corresponding the real experimental situations in crystals has been done. Acoustical anisotropy, light diffraction, and interference are taking into account. It helps to find restrictions and possibilities for the SAW velocity measurement utilizing the two-beam optical interferometer. The new measurement algorithm and scheme for the SAW velocity studding that increases the methods possibilities are described
