研究了一种偏振分布反馈光纤激光传感器，用于测量室温至250/spl deg/C范围内的流体压力，测量范围可达50 MPa。各向同性压力直接作用在光纤上，这消除了对机械换能器的需要。约20千帕（0.2巴）的压力分辨率被证明。此外，保护石英光纤免受流体和各种光纤涂层对传感器响应的热机械效应的恶化进行了研究。
A polarimetric distributed feedback fiber laser sensor for the measurement of fluid pressure up to 50 MPa is investigated between room temperature and 250/spl deg/C. The isotropic pressure acts directly on the fiber, which eliminates the need of a mechanical transducer. A pressure resolution of about 20 kPa (0.2 bar) is demonstrated. Furthermore, the protection of the silica fiber against deterioration by the fluid and the thermomechanical effects of various fiber coatings on the sensor response are studied.
