Opto-acoustoelectric device and methods for analyzing mechanical vibration and sound |
摘要 |
An opto-acoustoelectric device encompasses a diaphragm having a diffraction grating, the diaphragm is susceptible to a vibration driven by an external force; a light source oriented to irradiate the diffraction grating; and a photo detector configured to detect the light diffracted by the diffraction grating and to convert the detected light into an electric signal. The electric signal corresponds to a displacement of the vibration in the diaphragm.
