APPLICATION OF A DIRECTIONAL INTERFEROGRAM RECORDING SCHEME TO DETERMINE THE MOVEMENT OF AN OBJECT USING A HOLOGRAPHIC INTERFERENCE INSTALLATION

The work is devoted to the study of object movement using the method of holographic interferometry according to a codirectional scheme. This work is relevant and promising because coherent optics methods play a significant role in optical measurements, and holographic interferometry methods are among the most highly informative and high-precision approaches. The article sets the goal and objectives as well as defines the object and method of research. The appearance, optical scheme. and technical parameters of an experimental holographic interference installation are given. Interference fields for various types of movements are shown, as well as a scheme for reproducing an interferogram after recording object movements. The results of moving the object image along the X axis by 100 microns and along the Z axis by 150 microns were obtained, and the relative error of determining dx and dz, which does not exceed 5%, was revealed.
