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. Substâncias fluorescentes emitem energia fluorescente quando estimuladas por luz de um determinado comprimento de onda (espectro estimulado). Depois que o incentivo for revogado, a persistência do brilho residual da fluorescência depende de fatores como as características da substância fluorescente e a temperatura ambiente. Esta fluorescência excitada normalmente decai exponencialmente, e nos referimos à constante de tempo de decaimento como tempo de vida da fluorescência ou tempo de pós-luminescência da fluorescência. FJINNO descobriu através de experimentos que a atenuação do brilho residual da fluorescência varia sob diferentes temperaturas ambientais. Portanto, medindo a duração do tempo de vida do brilho residual da fluorescência e processando-o através da seção de demodulação de fibra óptica, a temperatura ambiente naquele momento pode ser determinada.
