Advanced intensity-modulated fiber sensors for scalable sensing
Among the various classes of fiber optic sensors, intensity-modulated fiber optic sensors (IM-FOSs) stand out due to their structural simplicity, low cost, and ease of implementation.
Fiber-optic sensor
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.
Fiber Optical Intensity Sensors
Fiber optical intensity sensors are made of optical fibers connected to a miniaturized optical sensor which is based on either a mechanical light valve, a light scattering process, a photoemission or
