This paper presents a fluorescence fiber probe design for temperature sensor based on lifetime measurement and focuses on the structural and coupling analysis between the stimulated fluorescence area to light-source and optic fiber. A theoretical model taking advantage of geometric optics is built to estimate the effectiveness of the probe design. A standard 62.5/125μm multimode fiber with a spherical end and least squares fitting method are adopted in the sensing system to demodulate the fluorescence lifetime. Experiment results of temperature range from 17°C to 77°C demonstrate an efficiency increment of 82.36%, which matches well with the simulation.
