光纤环衰荡光谱（FLRDS）是一种吸收光谱和检测技术。它利用光学腔，不仅实现了通过样品的长有效路径长度，而且消除了光强度波动的影响。本文介绍了FLRDS在气体浓度、压力、应变、折射率等传感器方面的研究进展。根据其不同的传感特性，详细介绍了其在传感器中的各种应用的工作原理和性能。最后，总结了FLRDS在传感技术方面存在的关键问题，并对未来的研究方向进行了展望。
Fiber loop ring-down spectroscopy (FLRDS) is an absorption spectroscopic and detection technique. It makes use of an optical cavity, which not only realizes a long effective path length through a sample, but also eliminates the effects of fluctuations of the light intensity. In this article, research advances of FLRDS used for sensors, such as concentrations of gas, pressure, strain, and refractive index are presented. According to its different sensing properties, the working principles and the performances of each application in sensors are introduced in detail. Finally, the key problems of FLRDS in sensing technology are concluded and the future research directions are discussed.
