Fiber-optic CAN measurement module for temperature readings
Universal fiber-optic measurement module
FBG sensors consist of a glass fiber into which one or more fiber Bragg gratings are inserted. These fiber Bragg gratings are formed when the refractive index of the glass fiber is cyclically changed during manufacture under the influence of a laser. When the glass fiber is illuminated, a characteristic wavelength is now reflected and this wavelength changes under strain.
