一、引言随着现代工业与科学技术的发展,对压力的测量提出了越来越高的要求。现已制成了各种类型的压力传感器。而具有不怕电磁干扰,可用于易爆场合等一系列优点的光纤压力传感器,则受到了人们的日益重视。压力传感器一般多为令待测压力作用在能发生弹性形变的弹性体上,由测定弹性体的形变来确定压力。这种形变一般表现为微位移。显然,测量微位移的有效方法是应用光学干扰仪。我们在参考Elric W.Saaski 等人工作的基础上,根据现有条件研究了透射式Fabry-Perot 干涉腔型的光纤压力传感器。
I. INTRODUCTION With the development of modern industry and science and technology, more and more high demands are placed on the measurement of stress. Various types of pressure sensors have been made. And has not afraid of electromagnetic interference, can be used for a series of advantages such as explosion-prone optical fiber pressure sensor, it has been the people’s attention. Pressure sensors are generally more for the pressure to be measured on the elastic deformation of the elastic body can be determined by measuring the deformation of the elastomer to determine the pressure. This deformation is generally manifested as micro-displacement. Obviously, an effective method of measuring micro-displacement is the use of optical interferometers. Based on the work of Elric W. Saaski et al., We study the transmission Fabry-Perot interferometric cavity fiber optic pressure sensor based on the existing conditions.
