Home / The function of fiber optic stress sensors
Fiber optic strain sensors are an innovative solution designed to measure deformation. These sensors utilize the unique properties of light traveling through fiber optic cables to detect and quantify strain caused by environmental or structural changes. This paper conducts a systematic analysis of the sensing mechanisms in fiber-optic pressure sensors, with a particular focus on the performance optimization effects of fiber structures and materials, while elucidating their application characteristics in different sensing scenarios. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time.
