Gas-Flow Sensor using Optical Fiber Bragg Grating(FBG)
Journal of Navigation and Port Research, 2008 We have proposed and demonstrated an gas-flow sensor using optical fiber bragg grating(FEG). The flow sensor has no electronics and no mechanical parts in its sensing part and the structure is th11s simple and immune to electromagnetic interference(EMI). The FEG sensor was consisted qf the sensing element and a coil heater.
