中文摘要:
      将光纤传感技术与传统的红外水分测定方法相结合,设计了一种光纤束传感器来实现发射光和接收光的传输.为将接收二极管上的微弱信号送到A/D转换器处理,采用锁定放大原理设计接收信号的调理电路.在不影响测量精度的情况下,能使红外水分测定系统变得更简单、更廉价.
英文摘要:
We introduce a method to combine the technology of fiber sensor with the tradition infrared moisture detector, and design a kind of fiber bundle sensor to carry out the transmitting signal and receiving signal. We use the principle of lock - in amplifier to amplify the weak singal and send it to A/ D conversion properly. Under the condition of fitting for every quality target, we make the entire system more simpler and cheaper.
