Abstract

Pressure gradient vector probes are adversely affected by diffraction around internal components of the probe; however by constructing a pressure gradient probe from polyvinylidene difluoride (PVDF) sensor elements, which have acoustic impedance similar to seawater, the diffraction effects within the probe can be effectively minimised. For use in a pressure-gradient intensity vector probe though, the elements must be omni-directional. This paper discusses the design, construction and initial characterisation of a prototype two-dimensional pressure-gradient vector probe using four PVDF films as the sensing elements.
