Abstract
A fiber optic acoustic sensor that detects pressure waves from all incident angles features multiple mandrels orthogonally disposed to provide omni-directional sensing capability. The topology of the mandrels prevents frequency response drop-off characteristic of cylindrical sensors at wavelengths smaller than ½ the length of the acoustic cylinder. The larger operating bandwidth and omni-directional sensing capability makes this fiber optic acoustic sensor a suitable choice for a wide range of applications.
