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. Zat fluoresen memancarkan energi fluoresensi ketika distimulasi oleh cahaya dengan panjang gelombang tertentu (spektrum terstimulasi). After the incentive is revoked, persistensi pijaran fluoresensi bergantung pada faktor-faktor seperti karakteristik zat fluoresen dan suhu lingkungan. Fluoresensi yang tereksitasi ini biasanya meluruh secara eksponensial, 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. Karena itu, 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.
