| Abstract: | The fluorescent lifetime detection technology,as the key technique ot optical fiber fluorescence temperature sensor, has been studied. The temperature measurement method based on the fluorescent lifetime is proposed. This scheme is based on using reference signal, and the exciting light that can he modulated as the sinusoidal phase-locked detection. The mathematic model based on the measurement of fluorescent lifetime has been derived. This method restricts the leakage of exciting light to improve the measurement precision. The experiment shows that this method is valid and meets the requirement for the temperature measuring system. |
