基于法布里-珀罗（Fabry-Perot,F-P）腔的干涉原理，提出了一种新型超高压力灵敏度的可压缩光纤微型F-P腔。该压力传感器的FP腔是将单模光纤（Single Mode Fiber，SMF）与石英管熔接后浸入水中在SMF端面处形成的空气泡来构成，其压力灵敏度大于1000nm/kPa。该光纤微型F-P腔在高灵敏度压力测量和水声传感方面有着潜在的的应用价值。

We propose a pressure sensor based on a micro air bubble at the end facet of a single mode fiber spliced with a silica tube.When immersed into liquid such as water,the air bubble acts as a Fabry-Pérot interferometer cavity.The pressure sensitivity is >1000 nm/kPa.The Fabry-Pérot interferometer cavity is expected to have potential applications in highly sensitive pressure and/or acoustic sensing.
