2-D LASER DOPPLER VIBROMETER

Sang Bo,Zhao Hong,Wang Xueli,Tan Yushan Research Institute for Laser and Infrared Applications,Xi′an Jiaotong University,Xi′an 710049  
In this paper,the fundamentals and method of 2 D Laser Doppler Vibrometer are introduced.The factors influencing the measuring accuracy are analyzed.Moreover,the circuit in singal processing is designed.The vibrating amplitude and frequency of 2 D vibration in wider range can be measured simultaneously in non contact means,the measuring results are accurate.
