| Abstract: | A space division multiplexing system of optical fiber MEMS Fabry - Perot pressure sensors based on virtual instrument is presented, which realizes real-time quasi-distributed measurement with several optical fiber Fabry - Perot sensors. A data acquisition and analysis system based on the virtual instrument technique is designed. Pressure on the sensor is demodulated by Fourier Transformation and other processing of the reflected signal of the sensor. The realtime reflected signal and pressure of sensor are displayed on graphical interfaces and can be saved. The experimental results demonstrate that the system has reasonable linearity, sensitivity and precision. Quasi-distributed measurement of the pressure is realized with easy operation and fast response speed. |
