Abstract

The transducer uses an annular crystal of the 3 m class operated in the shear mode with the shearing surfaces and the axis of the acceleration parallel to the Z axis of the crystal. When the crystal is composed of lithium niobate or lithium tantalate, the transducer has high efficiency and when the crystal is composed of lithium niobate it operates effectively over a very wide range of temperatures, including high temperatures above 1,000 deg.F.
