Paper Abstract

This paper analyses several wavelength demodulation methods based on optical fiber Fabry-Perot tunable filter. In view of the shortcomings of these methods, we proposed a real-time data acquisition method and a simple and effective demodulation algorithm based on optical fiber Fabry-Perot tunable filter and set up a temperature sensing system. The sensing system consists of an FBG sensor part, a data acquisition part, a data demodulation part and a data display part, we introduce the operation of the data acquisition part by explaining how the hardware and software work. Then we introduce the method of data demodulation we proposed, and demonstrated the steps of data demodulation in detail. We test the performance of this data acquisition part by carrying out a temperature sensor experiment, and prove the effectiveness of the demodulation algorithm at the same time. In addition, most programming languages can implement this simple and effective algorithm.
