We describe a low-cost fiber optic sensor for measuring photosynthetically active radiation (PAR) in turbulent flow. Existing technology was combined in a novel way for probe development addressing the need for a small but durable instrument for use in flowing water. Optical components including fiber optics and a wide-spectrum light detector were used

A fiber-optic temperature sensor
Automation and Remote Control, 2013In this paper we demonstrate the feasibility of designing a fiber-optic temperature sensor based on the principles of low-coherent tandem interferometry; the sensitive element represents a plane-parallel plate produced from fused silica of thickness 500 µm (the corresponding measurement range is between 40 and 90°C).

Fiber Optical Intensity Sensors
IEEE Journal on Selected Areas in Communications, 1983Fiber optical intensity sensors are made of optical fibers connected to a miniaturized optical sensor which is based on either a mechanical light valve, a light scattering process, a photoemission or photoabsorption process, or the transmission property of the optical fiber itself.

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.

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 ...

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.

Annals of Biomedical Engineering, 1983
The theory, construction and performance of a catheter tip optical PCO2 probe is described. The sensor, called the Opticap, is made with plastic fiber optics. One fiber carries light to the sensitive tip which is a silicone rubber tube 0.6 mm dia. X 1.0 mm long filled with a phenol red-KHCO3 solution.

Fiber-optical sensors as transducers
IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2003The paper considers a possibility of using fiber-optical sensors (FOS) as transducers. There are described and compared main advantages and disadvantages of analogue and pulse FOS. There are presenting results of estimating of metrological and quantitative precise opportunities of analog FOS.
