Plastic fiber optic sensor for continuous liquid level monitoring
Sensors and Actuators A: Physical, 2019The study demonstrates the development of a novel low-cost plastic optical fiber (POF) based sensor for liquid level measurement. The sensor works on the principle of reduction in scattering-based optical losses (in contrast to the increase in optical ...

So far, I have concentrated on how optical fibers are used for communications. However, fiber optics also have other important uses. This chapter will show how fibers are used as sensors. Fiber sensors work in a variety of ways, sometimes just using fibers to deliver light, other times monitoring changes induced in light transmission caused by external

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.

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.

Microstructured Optical Fiber Sensors
2007 9th International Conference on Transparent Optical Networks, 2007Microstructured optical fiber (MOF) sensors are nowadays utilized or proposed for the measurement of a large variety of physical and chemical parameters, e.g. in environmental and biological applications because of their efficiency and versatility. This paper, at first, gives a short review of MOF sensors reported in literature. An evanescent field MOF

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.
