Research of the Absorption of Human Skin and its Detecting Platform in the Process of Laser Cosmetology

摘要

Because of the melanin, hemoglobin and water molecules, etc. containe,d light absorption of human skin tissue changes with wavelength of light. This is the principle used in laser cosmetology for treating pigment diseases and vascular lesion desearses as well as skin decoration such as body tattooing, eyebrow tattooing, etc. The parameters of treatment used in laser cosmmetology principally come from the research of the skin tissue optical characteristics of whites, and it is not suitable for the Oriental. the absorption spectrum of yellow race alive skin has been researched. The detecting platform for use in the measuring of vivi-tissue absorption spectrum has been developed which using opto-electronic nondestructive testing and virtual instrument techniques. The degree of pathological changes of skin can be detected by this platform also, thus the shortcoming of dosage selection in laser clinical treatments which have been decided only by naked eye observation and past experience of doctors can be solved.
