【摘要】 光纤法珀传感器具有测量精度高、动态范围大、可单端检测等优点。针对白光干涉型法珀传感器,设计了一种基于体光栅的光纤传感器解调系统。该系统采用高性能体光栅和线阵 CCD 阵列实现了光谱的采集,并结合高性能数据采集卡和 PC 机进行信号的处理和输出。测试结果表明该解调系统的温度测量精度在±1℃以上。更多还原

【Abstract】 Fiber optic Fabry-Perot sensor has many advantages such as high accuracy,large dy- namic range,and‘point’sensing.A white-light interferometric fiber optic Fabry-Perot sensor de- modulation system based on volume grating and linear CCD array were desiged.The high accura- cy acquisition card and PC were used in data acquisition and signal processing.The performance of the demodulation system was tested.The result shows that the demodulation system achieveds the accuracy of±1℃.更多还原
