Research Of The Absorption Of Human Skin And Its Detecting Platform In The Process Of Laser Cosmetology

Photon-tissue interactions and photo-biomedical detection are the hotspots of current biomedical photonics research. The light absorption of human skin tissue changes with different wavelength of light. Melanin, hemoglobin and water molecules are the main factors causing skin absorption. The principle of selective absorption of skin tissue is just used in laser cosmetology for treatment of pigmented diseases and vascular lesions diseases as well as body tattooing. In laser cosmetology, light absorption research of yellow races vivi-skin and establishment of detecting platform are of great importance to fundamental research and clinical treatment. Establishment of a detecting platform using optoelectronics and virtual instrument used for detecting the light absorption of human skin tissue is described, which realized the real time and nondestructive detecting of vivi-skin tissue in clinical treatment. Normal skin tissue and some skin tissue with pathological changes are tested by this detecting platform, the absorption spectrum are obtained. The degree of pathological change of skin can be detected by this platform quantitatively, thus give assistance to the determination of suitable treatment parameter in laser cosmetology.
