| Abstract: | An optical fiber temperature sensor based on the temperature dependence of differential spectral reflectivity of dielectric multilayer interference filter is described. The ratio of the reflected light powers at two different wavelengths is used as the output of the sensor, in order to eliminate the influence of changes in the output power of the light source on the measurement results. The experimental results show that this measurement method is realizable. |
