EXPERIMENTAL DETERMINATION OF AN OBJECT DISPLACEMENT MAGNITUDE IN THE INSTALLATION PLANE USING THE HOLOGRAPHIC INTERFEROMETRY METHOD
Annotation
The features of the functioning of an experimental setup based on application of two-frequency laser radiation using the method of two exposures of holographic interferometry are studied. The installation is intended to determine the amount of movement of an object along the OX axis in the plane of its installation. The holographic interferometry method ensures long-term storage of information on photo carriers, allows for maximum contrast of the interference pattern and high-quality reconstruction of wave fronts. The appearance, optical design and technical characteristics of the experimental setup are presented. Expressions are obtained to determine an object displacement magnitude and measurement
