Abstract

This work is devoted to the study of digital holographic interferometry as a method for non-contact examination of micro-objects. The text discusses the physical principles of holography, which are based on the superposition of reference and object light waves. It describes the process of recording an interference pattern using electronic matrices and its subsequent processing in a software environment. The main stages of the work are highlighted: from the formation of a laser beam to the acquisition of a digital hologram. Particular attention is paid to the possibility of numerical focusing, which allows the object to be studied at different distances after recording. The role of digital methods in restoring the three-dimensional structure of microscopic elements is considered. The promising use of artificial intelligence to improve image quality and reduce noise is also mentioned. Finally, the main technical difficulties are highlighted, such as the sensitivity of the system to vibrations and the high demand for computing resources.
