Abstract
The method of remote micro-vibration measurement is studied and presented based on the laser feedback effect in this paper, and the key factors of remote vibration measurement are analyzed. The vibration measurement system is designed and built based on the laser feedback and the research of the remote micro vibration measurement is carried out. The system has ultrahigh measuring sensitivity and the working distance is 25 meters, which can measure the vibration of non-cooperative target. The system has the capability to realize the non-contact measurement of remote micro-vibration at different driving signals,and can fulfill the complex vibration measurement and reproduction of multiple frequencies. It can identify the voice signal,and the voice signal reproduced is clear to hear. The system can meet various requirements of vibration measurement and has great significance in practical application.
