荧光寿命检测被广泛用于感测物理和化学量。基于荧光寿命的传感系统在时域或频域中的测量精度依赖于它们对叠加到噪声的低电平信号的检测和分析能力。在这项工作中，通过使用基于光纤温度传感器系统的实验装置，对用于估计荧光寿命的几种数据处理和分析方法进行了定量评估。使用来自光学感测介质的实际信号进行各种方法之间的比较。本文还回顾和讨论了时域和频域寿命测量的基本原理，指出了连续频域方法的局限性，并提出了克服这一局限性的方法。研究的寿命间隔为200 ~ 2200μs，对应于传感器的温度范围约为300 °C。结果表明，随着时间的推移，...
Fluorescence lifetime detection is widely used for sensing physical and chemical quantities. The measurement accuracy of fluorescence lifetime-based sensing systems, either in time or frequency domain relies on their capability of detection and analysis of low level signal superimposed to noise. In this work a quantitative assessment of several data processing and analysis methods for the estimation of the fluorescence lifetime was carried out by using an experimental arrangement based on a fiber optic temperature sensor system. A comparison between the various methods was performed using actual signals from an optical sensing medium. The basic principles of time- and frequency-domain lifetime measurements were also reviewed and discussed in order to point out the limit of the cw frequency-domain approach and to suggest a way to overcome it. The investigated lifetime interval was from 200 to about 2200μs, corresponding to a temperature span of the sensor of about 300 °C. The results showed that in time do...
