Development And Applications of Fiber Bragg Grating Accelerometers

Over the past few years, Fiber Bragg Grating (FBG) accelerometers have seen rapid growth due to their inherent properties, including magnetic immunity and high sensitivity, leading to their increased deployment in environments with extreme conditions or as improved alternatives to traditional sensors. In this article, the development of FBG accelerometers is discussed from three distinct perspectives: low-frequency sensors, high-frequency sensors, and multi-dimensional sensors, highlighting advancements made in recent years. The text also delves into the application domains of such sensors and offers a projection for future developments. It is forecasted that FBG accelerometers will maintain their current trajectory of advancement over the coming years, with more scholars anticipated to propose novel sensor designs based on different structures, either improving upon existing ones or integrating them with other forms of sensing technology. Notably, these sensors are not only expected to find further applications in sectors such as oil exploration and seismic monitoring but are also likely to experience expanded use in aerospace and other specialized domains.
