The sound detection technology is the base and premise of acoustic research,and it has wide application in many fields.Base of the microchip solid-state laser feedback and frequency-shifted method of phase measurement,the sound detection system is built with Nd∶YVO4 microchip laser.The system can detect and reconstruct the sound signals of different frequencies by measuring the vibration,and the reconstructed signal is clear and distinguishable.The system realizes the non-contact detection without setting a special target in the sound fields and remote measurement.So it can meet various requirements of sound detection and has great significance in practical application.
