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.

Brillouin fiber optic current sensor
Optical Review, 1996A novel reciprocal Brillouin fiber optic current sensor has been developed and tested. The sensor shows a sensitivity of 126 Hz/A that is very close to the maximum sensitivity obtained by using fibers without linear birefringence. The limitations due to the Kerr effect and optical feedbacks in the system are also investigated.

Fiber optic technology started in 1970’s, for long distance telecommunications, and it has experienced an exponential growth during the last four decades. Sensing applications are a small spin-off from this technology, taking profit of developments done for optoelectronic components and concepts. Optical fibers are cylindrical dielectric waveguides for

The development of fiber-optic technology was mainly driven by the requirements of the telecommunications industry. Nonetheless one should not overlook that telecommunications is not the only application of fiber optics. The other major application area is in metrology and data acquisition.

Fiber-Optic Based Cell Sensors
2009Different whole cell fiber optic based biosensors have been developed to detect the total effect of a wide range of environmental pollutants, providing results within a very short period. These biosensors are usually built from three major components, the biorecognition element (whole-cells) intimately attached to a transducer (optic fiber) using a ...

Fiber optic polymer cure sensor
Journal of Lightwave Technology, 1988An in situ method is presented for monitoring the curing of polymeric compositions, including epoxy- and polymide-based composites. The sensor measures the difference between the refractive index of the cured and uncured composition, with the index increasing as polymerization proceeds.

Fiber-optic sensor for humidity
Optics Letters, 1989A novel fiber-optic humidity sensor is described. It is based on reversible sorption of water from the ambient atmosphere in a porous thin-film interferometer that sits on the tip of a fiber. The sorbed water changes the refractive index of the thin films and thus the reflectivity of the interferometer; the resulting modulation of the reflected ...
