Abstract

To develop methods of skin disease diagnostics and treatment monitoring, experimental investigations of the laser beam scattered by epidermis thin layers have been carried out. The coherent optical analyzer (COA) has been developed to analyze typical structures in the human upper skin layers. By means of the COA, the spatial distributions of epidermis strippings amplitude-phase transmission functions were investigated. The spatial power spectrum's instantaneous values registration for various spatial frequencies at the mechanical scanning of a direction, normal to the system's optical axis, was carried out. The registration was fulfilled by means of a specialized pulse- counting register of photoelectric signals.
