Abstract
A system for sensing optical fiber temperature includes a laser that produces a first electromagnetic spectrum. A first optical filter receives the laser output and reflects it. The first optical filter transmits electromagnetic radiation having greater and lesser wavelengths than the laser output. The transmitted light reaches a second optical filter which reflects the light of lesser wavelength, but transmits the light of greater wavelength. A first detector is placed to received the reflected, lower-wavelength light and a second detector is place to receive the transmitted, higher-wavelength light.
