The article solves the problem of increasing the objectivity of visual analysis of internal organs during surgery. The authors found that the spectral characteristics in the visible reflection spectrum allow the practicing surgeon to determine the presence of pathologies of the internal organs, as well as the location of their borders. The paper considers the existing methods for assessing the viability of biological tissues, the most promising one is selected. A description of the proposed device that implements the proposed method and a description of the program executed in the LabView environment is given. The work also presents a methodology for determining the optical parameters of the studied biological tissue of a group of conditionally healthy people, conducted statistical processing of data obtained experimentally and determined normal values.
