Abstract: Fiber microcavity sensors have gained widespread attention in the feld of optical fber sensing due to their inherent safety, small size, low cost, and resistance to electromagnetic interference. Fiber microcavity Fabry-Perot interference sensors features with multiple measurable parameters and the capability of simultaneous measurement of multiple parameters. This article reviews the research progress of the fber microcavity Fabry-Perot interference sensors in various sensing scenarios, such as temperature, pressure, liquid refractive index, hydrogen concentration, organic volatiles concentration and so on, and introduces the manufacturing method, sensing principle and experimental results of the sensors in detail.

Key words: optical fber sensor, optical fber microcavity, Fabry-Perot interferometer, multi-parameter measurement
