Abstract

The research results of autodyne signal formed under reflection of semiconductor laser radiation from vibration reflector have been presented. The influence of feedback coefficient and distance to vibration object on autodyne signal form has been shown. The method of reverse problem solution in autodyne interferometry of nonharmonical vibrations has been described. The suggested method allows to restore the amplitude and form of mechanical vibrations for autodyne system developed for interference system separated from the light source.
