Abstract
A fiber optic hydrophone structure comprises a casing around which is wound an optical fiber. The casing includes complementary top and bottom diaphragm members that mesh together and which are separated by a spacer ring. The spacer ring is tapered to knife edges which abut the inside surfaces of the top and bottom diaphragm members. The spacer thus acts as a fulcrum when a seismic signal causes motion of the diaphragms.
