Optical fibre sensors are an essential subset of optical fibre technology, designed specifically for sensing and measuring several physical parameters. These sensors offer unique advantages over traditional sensors, making them gradually more valuable in a wide range of applications. They can detect extremely small variations in the physical parameters they are designed to measure, such as analytes in the case of biosensing. This high sensitivity allows them to detect subtle variations in temperature, pressure, strain, the refractive index of analytes, vibration, and other environmental factors with exceptional accuracy. Moreover, these sensors enable remote sensing capabilities. Since light signals are used to carry information, the sensing elements can be placed at distant or inaccessible sites and still communicate the data back to the central monitoring system without signal degradation. In recent times, different attractive configurations and approaches have been proposed to enhance the sensitivity of the optical fibre-based sensor and are briefly explained in this review. However, we believe that the choice of optical fibre sensor configuration should be designated based on the specific application. As these sensors continue to evolve and improve, they will play an increasingly vital role in critical monitoring and control applications across various industries.
光纤传感器是光纤技术的一个重要子集，专门设计用于传感和测量多个物理参数。与传统传感器相比，这些传感器具有独特的优势，使其在广泛的应用中逐渐变得更有价值。它们能够检测其所设计测量的物理参数中极其微小的变化，例如在生物传感中检测分析物。这种高灵敏度使它们能够以极高的精度检测温度、压力、应变、分析物的折射率、振动和其他环境因素的细微变化。此外，这些传感器还具备遥感能力。由于光信号用于承载信息，传感元件可以放置在遥远或难以到达的位置，并且仍然能够将数据传输回中央监测系统而不会出现信号衰减。近年来，人们提出了不同的引人注目的配置和方法来提高基于光纤的传感器的灵敏度，本综述将对其进行简要说明。然而，我们认为应根据具体应用来选择光纤传感器的配置。随着这些传感器不断发展和改进，它们将在各个行业的关键监测和控制应用中发挥越来越重要的作用。
