DISTRIBUTED TEMPERATURE SENSOR ENHANCEMENT BY STIMULATED RAMAN SUPPRESSION |
摘要 |
A distributed temperature sensor and a method of determining temperature are described. The distributed temperature sensor includes an optical fiber to filter or remove Stokes Raman scatter and prevent stimulated Raman scatter and a light source to inject light into the optical fiber. The distributed temperature sensor also includes a photodetector to detect light energy resulting from the light injected into the optical fiber, the light energy including anti-Stokes Raman scatter and Rayleigh scatter; and a processor to determine temperature based on a ratio of the anti-Stokes Raman scatter and the Rayleigh scatter. |
