摘要
提出了一种强度调制型光纤传声器的设计。该设计使用束型光纤用于传送光线和接收反射光线,并提出四点接触式MEMS反射膜片结构,给出了ANSYS仿真结果。该光纤传声器具有较好的光耦合效率,使后续放大电路设计更加简便。
An intensity modulated optic microphone is introduced. The fiber bundle to transmit and receive light is used. It contains a configuration of MEMS reflect-membrane about four points contact and its ANSYS simulate result. The optical microphone has a better light-coupling efficiency and a higher sensitivity, and makes amplify circuit design more simple.
