| Abstract: | A novel reflective fiber optic microphone is presented. It uses the structure of Y type reflective multimode fiber sensing probe. Also, we give a mathematics model based on the theoretical research of the fiber optic sensing probe, from which we get a calculative formula of the receiving optical intensity, and analyze the optical intensity modulation property. Besides we design a structural scheme of the fiber optic microphone system from the theory and experiment. |
| Keywords: | fiber-optic microphone fiber-optic sensing probe with single tube and many membranes reflecting and optical intensity modulating coupler |
