Abstract: Disclosed are a temperature measurement method using the fluorescence characteristic of an optical material having temperature dependence and a temperature sensor technology using the same. According to the present disclosure, the temperature measurement technology using the fluorescence signal intensity ratio has a self-compensation function to reduce optical signal noise caused by fluctuations in light source output and optical waveguide loss, and uses two fluorescence signals with a strong fluorescence signal intensity to solve the existing disadvantage of generating a lot of noise due to a low fluorescence signal.
