Paper Abstract

The paper describes investigations of vibrations by the laser interferometry where both beams are offset in frequency. This method is called the laser heterodyne vibrometry. The main aim of this investigation was heterodyne detection of a weak laser light scattered from a vibrating object. As a standard surface we used a piece of white zero sheet connected to the vibrating object.
