Tasks: 1.Construct graphs of the reflection coefficients of nerve fibers compared to other organs: spleen, liver, heart, bladder, lung, kidneys, muscle, skin, subcutane-ous fat, pancreas. 2.Approximate the reflection coefficients of biological tissues using a poly-nomial function. 3.Construct graphs of the spectral power distributions of surgical illumina-tors. 4. Calculate the color coordinates on the CIE 1931 chromaticity diagram. 5. Calculate the color and lightness contrasts of nerve fibers. 6. Justify the selection of an LED light source to enhance visual contrast. The study involved modeling the color coordinates of various biological tis-sues on the CIE 1931 chromaticity diagram, taking into account their reflectance within the wavelength range of 410—750 nm. The spectral characteristics of surgi-cal lighting sources were analyzed, and lightness and color contrasts of nerve fibers relative to other tissues were calculated under various lighting conditions. The results confirm that the RGB LED source provides the highest distinguishability of nerve tissue, and the proposed recommendations can be used to optimize surgical lighting.
