Abstract :
Many theoretical studies prove the SAW gyroscopic effect and presume that the rotation sensitivity character is of interest for the development of rotation sensors, but these studies are insufficient experimental proofs. The effect of Coriolis force on SAW is analyzed and testified by experiments in this paper. The Christoffel´s equation including Coriolis force and its numerical results are obtained. A device with a dual-channel delay line is developed using LiNbO3 substrate to do experiments. The results shown the SAW gyroscopic effect is existence.
