Abstract

Fiber optic levers have been found useful in the design of intracardiac pressure transducers, low displacement biological measurements, and more generally as noncontact optical proximity detectors. In this paper the utilization of a bifurcated fiber optic lever in the design of hydrophones of the pressure and pressure gradient types has been considered. This approach leads to simplicity, low cost, and relative ease in implementation. Some optical and acoustical considerations are given to establish the validity of the experimental data presented. It is shown that with little effort these devices can provide acoustic sensitivities at least equivalent to those of piezoceramic elements within the same frequency range and can generate acceptable directivity patterns in the pressure and pressure gradient modes.
