What is a Fiber-optic Sensor? Fiber-optic sensors (also called optical fiber sensors) are fiber -based optical sensors for some quantity, typically temperature or
Some sensors measure at a defined point, others detect several discrete measuring points along a fiber, while so-called distributed methods enable a continuous profile over many kilometers. These are
Both interferometric and reflectometric fiber optic sensors are becoming popular for their ease of use, flexibility, long distance sensing, and potentially noise free
Fiber optic sensors have been widely used and studied in recent times. This paper presents operating principles and applications of fiber optic sensors namely reflectometric and
Optical fibers can be used as sensors to measure strain, temperature, pressure and other quantities by modifying a fiber so that the quantity to be measured modulates the intensity, phase, polarization, wavelength or transit time of light in the fiber. Sensors that vary the intensity of light are the simplest, since only a simple source and detector are required. A particularly useful feature of intrinsic fiber-optic sensors is that they can, if required, provide distributed sensing over very large distances.
The basic principles and mechanisms of photonic sensors are discussed, including the use of light to sense and quantify associated physical, chemical, or biological changes in their surroundings.
