DEEPWATER AIR-BACKED FIBER OPTIC HYDROPHONE FOR PRESSURE HOUSING ATTACHMENT

摘要

A hydrophone senses pressure waves. A hydrophone body attaches to a pressure housing endcap, and a hydrophone mandrel attached to the hydrophone body. A hydrophone body flange interposes the hydrophone mandrel and the pressure housing endcap, and a thickness of the hydrophone body flange is predetermined so than an inward deflection of the hydrophone body matches a compression of the hydrophone mandrel against the hydrophone body flange in presence of a constant hydrostatic load.
