Abstract
The main method of applying optical principles of operation of the system for diagnosing pathologies of biological tissue at an early stage is proposed to use the formation of moiré effects. The aim of the work is to create theoretical foundations for a method of early determination of the state of the structure of biological tissue of objects, which contributes to the intellectualization of diagnostic processes and exposure, in particular, to light electromagnetic fields. This improves the quality of equipping scientific experiments in biology and medicine with modern technologies. The proposed method of diagnosing the condition of objects allows its use in early diagnosis of pathologies and, as a result, in the treatment of a wide range of diseases, as well as, for example, postoperative scar structures, a number of dermatological diseases.
