Abstract
To develop methods of some skin diseases diagnostics and of these diseases treatment monitoring the experimental investigations of the laser beam scattered by epidermis thin layers have been carried out. For the analysis of the specific structures with typical sizes about 101 - 103 micrometers in the human upper skin layers the coherent optical analyzer (COA) has been developed. By means of COA the spatial distributions of epidermis strippings amplitude-phase transmission functions were investigated. The spatial power spectrum (SPS) instantaneous values registration for various spatial frequencies at the mechanical scanning of a pattern in direction, normal to the system's optical axis, was carried out. The registration was fulfilled by means of the specialized pulse-counting registrator of photo-electric signals. Well marked differences have been discovered between level crossing statistics for normal and psoriatic skin.
