。In an optical fiber hydrophone that applies a Fabry-Perot interferometer, a portion of one of two sets of optical fibers of the same quality and length having semipermeable membranes on both end faces is wound around the outer periphery of a first rigid cylinder to form a sensor section. The inner surface of the rigid cylinder is sound insulated with a sound insulating material, and a part of the other optical fiber (a second rigid cylinder that is sufficiently smaller than the first rigid cylinder by the same length as the optical fiber used as the sensor section) is installed. wrapped around the outer periphery, fixing the second rigid cylinder inside the first rigid cylinder, closing both ends of the first rigid cylinder and providing a plurality of small holes in the rigid cylinder, the first, Second
An optical fiber hydrophone characterized by a structure in which a rigid cylinder is filled with the same liquid and sealed in a cylindrical elastic container.
