description: The subject of the graduate qualification work is a skin sample 10x10 cm in size with a pronounced formation (mole). The given work is devoted to developing a radiation source with a controlled spectrum for obtaining monochrome images with a distribution of light intensity at a selected wavelength. As a result of the work, a method for multispectral image processing of skin areas was proposed. To implement the method, a layout of a multispectral light source has been developed. LEDs with wavelengths ranging from 385nm to 593nm were used as the light source. Calculations were carried out confirming the performance of the product. Images of a skin area were obtained when it was illuminated by LEDs with selected wavelengths. Digital image processing was carried out, during which graphs of the amplitude intensity distribution at the selected wavelengths were obtained, as well as equalization and image filtering were carried out for greater clarity. Conclusions were drawn about a higher coefficient of light absorption in places with neoplasms, as well as about obtaining more information when illuminated with wavelengths in the range from 385 to 470nm. The work was performed on the basis of research laboratory No. 235 "Radio and optoelectronic devices of bioinformatic and genomic technologies for early diagnosis of pathologies of living systems" Institute of Analytical Instrumentation RAS in St. Petersburg.
