摘要
本文提出了一种新型的反射式光纤microphone ,它把反射式光纤传感探头应用于传统的麦克风上,来实现对声波的调制.本文从理论和实验两方面给出了反射式光纤microphone的光强调制函数,并对反射式光纤microphone系统进行了研究.
A novel reflective fiber-optic microphone is presented,it uses reflective fiber-optic sensing probe on traditional microphone to modulate sound wave. This paper gives optical intensity modulating function of fiber-optic microphone in theory and experiment respectively. Furthermore, we introduce reflective fiber-optic microphone system.
