Fiber-optic hydrophone (FOH) is a significant type of acoustic sensor, which can be used in
both military and civilian fields such as underwater target detection, oil and natural gas …

In this letter, a distributed optical fiber hydrophone (DOFH) based on Φ-OTDR is
demonstrated and tested in the field. The specially designed sensitized optical cable with …

In this paper, we demonstrate a fully distributed hydroacoustic sensing based on the ultra-
highly sensitive and lightweight fiber-optic hydrophone cable assisted with heterodyne …

In this paper, we report the design and development of a fiber optic hydrophone for
underwater applications. The sensing configuration is based on a Michelson interferometer …

A high-performance fiber optic interferometric hydrophone based on a push–pull mandrel
structure, with high sensitivity and wide-frequency response, is designed and developed …

Fiber-optic interferometric sensing is a very attractive approach for creating lightweight, high-
sensitive, and fully passive fiber-optic hydrophone arrays. In this paper, results of sea trials …

A fiber-optic hydrophone based on an intensity-modulation mechanism is described. The
device possesses sufficient sensitivity to detect typical deep-sea noise levels in the …

The performance of an optical multilayer hydrophone for ultrasound measurements is
investigated both in theoretical terms and experimentally. The optical measurement system …

A large-aperture, seabed mounted, fiber-optic hydrophone array has been constructed and
characterized. The system is designed for use as a large area surveillance array for …

Optical fibre hydrophone systems have been developed in recent years for a variety of sonar
applications, and the technology has now reached a stage where it is able to compete with …
