IEEE SENSORS 2014 Proceedings, 2014
A fiber optic curvature sensor based on discrete Fiber Bragg gratings inscribed in a multi-core fiber is presented. The individual cores of the multi-core fiber are each interrogated by a custom-built spectrometer running at up to 20 kHz. They are interfaced with a custom-tapered combiner of single-core fibers fusion spliced to the multi-core fiber ...

Applied Optics, 1977
A new class of hydrophones is currently being developed, which utilize optical beams and interface directly to fiber optic transmission and processing links. Some of these sensors employ an optical fiber itself as the transduction element and possess significant advantages and versatility.

Multimode optical fiber sensors
1995Of the properties of light which can be conveniently modulated, phase and polarization information are immediately lost upon entering a multimode optical fiber. This leaves intensity as the only transmittable property available for use as a modulation sensitive parameter.

Distributed optical-fibre sensors
Journal of Physics D: Applied Physics, 1986A distributed optical fibre sensor is described. The sensor uses a sensor fibre (10) having a low or zero intrinsic birefringence that is responsive to an environmental parameter (24) such as pressure. Probe light pulses having a diversity of launch polarisation states are used to reduce signal fading and polarisation dependent loss in the retardation ...

Current Opinion in Chemical Biology, 2002
Imaging optical fibres have been etched to prepare microwell arrays. These microwells have been loaded with sensing materials such as bead-based sensors and living cells to create high-density sensor arrays. The extremely small sizes and volumes of the wells enable high sensitivity and high information content sensing capabilities.
