Laser doppler vibrometer using acousto optic devices for precision vibration measurement

The objective of the contact type acousto optic vibration measurement technique basically is to minimize the error induced in the system due to the environment and the vibration of optical components, not by introducing sensors, but by a common optical path. The common optical path is designed in su...
