摘要： A multi-channel remote audio monitoring device based on a heterodyne interferometric laser Doppler vibrometer. The multi-channel remote audio monitoring device_transmits two invisible laser beams to a reflecting surface being vibrated by sound sources in the proximity. Reflected beams constituting two channels are then received back and converted into audible signals for on-line listening and on-line storing. Aforementioned signals can also be processed for on-line noise reduction purposes through a graphical user interface and a filtering module.
