| Abstract: | In this paper, the working principle and the application status of distributed optical fiber temperature sensors are introduced briefly. The amplified spontaneous Raman scattering phenomenon in optical fiber and its time domain characteristics are analyzed. A new temperature measure principle based on the temperature effect of amplified spontaneous Raman scattering signals in optical fiber is put forward, and the new principle is applied to distributed optical fiber temperature sensor systems. Experiment phenomenon and data derived from the new principle are discussed in detail. |
