Abstract :
This paper discusses the disposal of audio signal of all fiber optic vibration sensor. Disvantages what electricity and light being combined together in traditional audio transmission cannot be divided has been overcome. The system also diminishes the interference from noise, electromagnetism, and so on. It also processes the advantage that can transfer audio signal in a long distance. Audio signal of this new fiber sensor also has been studied in the paper. Audio signal has been extracted and stored by using labview, and stored by using labview, and the noise reduction filter of audio signal has come true by matlab. At the end of the experiment, the result tells us that signal has been well extracted and stored through the disposal of matlab, audio noise has been decreased a lot.
