Laser Doppler Vibrometer for Long-Distance Acoustical Signals Acquirement

Not Accessible

Your library or personal account may give you access

Abstract

A laser Doppler Vibrometer (LDV) with a configuration of all fiber is developed according to the theory of the heterodyne detection. The system can be applied in an effective and high-sensitivity way to acquire the real-time acoustical signals through glass 20 meters away.
