Introduction to the Principle of Fluorescent Fiber Temperature Measurement

The fluorescence fiber temperature module consists of a fluorescence fiber demodulator and a fiber optic temperature probe. The fiber optic probe is composed of a fiber optic and a fluorescent object installed on top of it. Fluorescent substances emit fluorescence energy when stimulated by light of a certain wavelength (stimulated spectrum). After the incentive is revoked, the persistence of fluorescence afterglow depends on factors such as the characteristics of the fluorescent substance and environmental temperature. This excited fluorescence typically decays exponentially, and we refer to the decay time constant as fluorescence lifetime or fluorescence afterglow time. FJINNO found through experiments that the attenuation of fluorescence afterglow varies under different environmental temperatures. لذلك, by measuring the length of the fluorescence afterglow lifetime and processing it through the fiber optic demodulation section, the ambient temperature at that time can be determined.
