Концепт-проект цифрового спекл-флуориметрического дерматоскопа

Abstract

This paper presents the stage of development of a digital device for medical application, particularly in dermatology [1]. The device is designed to diagnose and monitor the course of malignant and benign neoplasms of the human skin. Physical phenomena for diagnostics in this device are the formation of laser subjective speckles and the skin fluorescence spectrum. In the analyzing process of sources and design solutions, structural and schematic diagrams were drawn up. The combination of speckle-interferometry and fluorescence diagnostics will allow combining in one device the function of tissue identification by the fluorescence spectrum and the capabilities provided by the assessment of speckles and interference bands. Statistical processing of laser speckles: estimation of blood flow rate based on averaged contrast, cell activity based on the frequency of speckles flickering, and holography of skin layers using speckle-interferometry.
