Status of Fiber Optic Acoustic Sensing
8th Optical Fiber Sensors Conference, 1992In the past few years a great deal of development effort has gone into fiber optic hy drophones for a variety of Naval applications. Significant demonstrations of fiber optic hydrophone technology have taken place in fixed undersea, towed array, submarine and Arctic environments.

Recycling optical fibers for sensing
SPIE Proceedings, 2016Optical fiber sensors has become one of the most promising sensing technologies. Within all the optical fiber sensing technologies, the Fabry-Perot interferometer (FPI) micro-cavities are one of the most attractive, due to the size, linearity and higher sensitivity.

Sapphire-Derived Fibers and Optical Fiber Sensing
2020The optical fiber being optical sensors exhibit several advantages including the immunity to the electromagnetic interference, simple structure, easy to carry, and large dynamic range. Especially, the possibility of working under harsh environment marks the fiber sensors that are superior to the electrical sensor counterparts.

Coupled-core optical fiber sensing
Optica Advanced Photonics Congress 2022, 2022The use of optical fibers with coupled cores is proposed for sensing applications. The interrogation of coupled-core fiber sensors is simple, fast and inexpensive as the parameter being sensed can be detected as intensity changes.

Optical Fiber Chemical Sensing Networks
SPIE Proceedings, 1987Many industrial processes or other phenomena of interest cannot be measured with conventional instruments because they are too hot, too cold, highly radioactive, or other-wise inaccessible to direct observation. Nuclear wastes stored in underground repositories, for example, will require in-situ monitoring.

Luminescent optical fibers in sensing
1998The development of fibers doped with materials through which luminescence is generated has a long history, which follows upon the original proposal by Snitzer [1] in the early 1960s of the use of an optical fiber geometry for lasers and optical amplification, employing 300 μm core diameter neodymium doped fiber.

Principles of Optical Fiber Sensing
2017Since the Nobel Prize award in 2009, received by Prof. Charles K. Kao, for his research and pioneering achievements regarding the transmission of light in an optical fiber, optical fiber has been regarded as one of the top inventions of the last decades revolutionizing not only telecommunications systems, but also new fields of applications such as ...

Fiber-Optical 3D Shape Sensing
2014Fiber Bragg grating (FBG) technology is well known since more than three decades. It started in 1978 with the discovery of photosensitivity in optical fibers by Ken Hill et al. [1] when illuminating germanium-doped silica fibers with visible argon ion laser radiation.
