Environmental Monitoring and Assessment, 2015
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

Fiber Optic Sensor Based on Vernier Microwave Frequency Comb
Journal of Lightwave Technology, 2019We demonstrate a proposed fiber optic sensor based on detecting the envelope of a Vernier microwave frequency comb (VMFC). A mode-locked fiber laser was employed as a microwave frequency comb source.

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

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

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.
