He-Ne激光透过人皮肤的研究

Experimental Research and Theoretical Analysis of He-Ne Laser Beam Penetration through Human Skin

本文通过测定黄种人的皮肤组织对不同强度的He-Ne激光的反射率和透射率,借助Kubelk-Munk物理模型分析了皮肤内的光强分布。得出:(1)皮肤对He-Ne激光的反射率及透射率与入射激光的强度关系不大;(2)反射率和透射率随皮肤的厚度及肤色不同而不同;(3)表皮层较真皮层的光强衰减要大。

In this paper we measured the reflectivity and transmittance of chinese people's skin with He-Ne lasers. The light intensity distribution of the incident ray in the skin has been analysed according to the Kubelk-Munk theory model. The results showed that (1) the reflectivity and transmisttance have nothing to do with the intensity of lasers; (2) the reflectivity and transmittance were correlated with the thickness and color of the skin; (3) the attenuation of light indensity in the epidermis is bigger than in the dermis.
