| Abstract: | The principle of distributed optical-fiber temperature sensor, based on Raman scatter and Brillouin scatter , is discussed by this paper , which adopts the frequency analytical method. The analytical method can overcome the shortcoming of the traditional temporal analytical method, which needs high-speed sample circuit. Furthermore the analytical method has broke a new path to enhance the spatial resolution of sensors. At the same time , a high spatial resolution optical-fiber sensor based on model coupling is discussed by this paper. Finally the comparison of several optical-fiber sensors are presented. |
