摘要：
The present invention provides for systems and methods for acquiring acoustic information from a resonating body. Specifically, a focused light beam is emitted from an emitter module onto an impedance matching reflector. The impedance matching reflector has similar wave propagation characteristics to the resonating body, so as to capture mechanical vibrations thereof. The impedance matching reflector reflects the focused light beam as it vibrates, and the vibrations are captured by a receiver module through the reflected light beam, which is converted to an input signal. The input signal may be further processed and converted to an audio output signal, as an accurate representation of the acoustic information emanating from within the resonating body.
