Sensors that vary the intensity of light are the simplest since only a simple source and detector are required.
Fiber optic temperature sensor wikipedia.
A fiber optic current sensor focs is a current sensor for measuring direct current.
The detector unit at the end of the sensor tube is equipped with gas sensors.
Distributed temperature sensing dts and distributed acoustic sensing das.
Optical fibers can be used as sensors to measure strain temperature pressure and other quantities by modifying a fiber so that the property to measure modulates the intensity phase polarization wavelength or transit time of light in the fiber.
Every increase in gas concentration results in a pronounced leak peak.
Temperatures are recorded along the optical sensor cable thus not at points but as a continuous profile.
