| Abstract: | A fiber-optic pressure sensor by counting interference stripe of Fabry-Perot(F-P) cavity is introduced,which can be used in some inflammable and explosive circumstance.The principle and the configuration parameters design of the sensor are described.Factors of error and future improvements are discussed.Experiment result shows the fiber-optic sensor with F-P cavity is simple in design,low in cost,excellent in anti-interference ability and precise in pressure detecting.It can reach 10 m in measurement range and 0.02 % in accurancy. |
