The system senses temperature by measuring fluorescence decay time. The fiber optic sensing probe is attached with rare earth fluorescent material, when rare earth material is excited by specific wavelength light, it will generate visible spectrum which is fluorescence. When the light stops, the time required for the fluorescence to decay depends on the rare earth material temperature . Normally higher temperature comes with shorter decay time.The biggest advantage of this temperature sensing technology is that the temperature measurement result only depends on the decay time of fluorescence, no other variables like intensity of light, transfer efficiency, and degree of coupling.
