摘　　要：传感器作为测量系统的一部分,已经成为系统高速、高质量、高安全性运行的保障。法布里-珀罗传感器更具有便携性、小型化的优点。为研究法布里-珀罗传感器的解调特性,阐述其主要解调方式(强度解调),并通过多个传感器联合解调,分析平行平板多光束干涉的原理,随着光程差的变化,光强产生周期性变化。基于强度解调方式,并联多个传感器解调,为今后新的传感测量系统提供参考。As a part of the measurement system,sensors have become the guarantee of high-speed,high-quality and high-security operation of the system.Fabry-Perot sensor has more advantages of portability and miniaturization.In order to study the demodulation characteristics of Fabry-Perot sensors,the main demodulation modes(intensity demodulation)are described.Through the mutual demodulation of multiple sensors,the principle of multi-beam interference of parallel plate is analyzed.With the change of optical path difference,the light intensity changes periodically.Based on the intensity demodulation mode,multi-sensors are demodulated in parallel.It provides reference for new sensor measurement systems in the future.
