In this recent testing and measurement trends devices which monitor a parameter of a system without disturbing working parameters of a machine is required. In mechanical structural products research, design, production and maintenance the Vibration measurement is becoming so much important. Laser Doppler Vibrometer is very important to control and in reduction of the noise levels in different fields of the engineering application. In the automotive industry, in reducing noise from engines, tyres, covers either to optimize vehicle cabin acoustics. In this paper, the basic working principle of of Laser Doppler Vibrometer, with the area of the structural acoustic analysis is described. Laser Doppler Vibrometer has large capability in experimental vibration testing in various industrial and research fields. It provides more advantages over traditional vibration measurements. The detailed review of the research work in various fields of Laser Doppler Vibrometry is discussed in this paper.
