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 ...

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.

An intrinsic fiber optic temperature sensor
IMTC/98 Conference Proceedings. IEEE Instrumentation and Measurement Technology Conference. Where Instrumentation is Going (Cat. No.98CH36222), 2000This paper deals with a new fiber optic temperature sensor. The relationship between temperature and refractive index of a "reference" liquid is used to obtain a sensing fiber output that follows temperature changes of an external fluid with very low response time.

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.

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 ...
