Distributed Fiber Optic Temperature Sensor | Yokogawa Canada

Fiber optic temperature sensor principle: This phenomenon is also true when you shoot a pulse of light (laser pulse) off of a molecule, in this case, the fiberglass molecule in the optical fiber cable. When the light source enters the optical fiber cable, most of the light bounces (backscatter) back unchanged (no change in wavelength).
