Abstract

Hybrid fiber-optical/silicon micromechanical sensing technique is a new technique which is recently developed in the world. In this paper, a new type of sound-optical array of microvibrators used as band pass filter gang is presented. The oscillating characteristic of microvibrators and the technique of detection has been analyzed by means of the fiber-optic intensity modulated microphone. The technique can extract sound spectrum features directly for the system of speech chinese recognition.
