摘要:

A device capable of measuring small displacements and vibrations of a moving body is presented. A small mirror, firmly attached to the object under investigation, deflects a pair of laser beams onto two distinct photodetectors. From the examination of the output signals, it is possible to have separate information on the rotational and translational movements of a surface.
