Optical Effects of Pigmentation on Temperature Rise in a Two-Layer Skin Simulant System During Irradiation.

摘要

It is demonstrated that from a knowledge of the thermal and optical properties of each layer of a two-layer system,together with the amplitude and distribution of the energy input,it is possible to predict temperature rises at depth in the second layer of a two-layer system. By varying the optical properties of the first layer and observing the temperature rises at depth in the second layer,the experimental results can be used to verify mathematical expressions for optical and heat transfer processes of the two layers. Such a system was devised to determine the thermal conductivity between a silicone rubber patch and the living skin irradiated. It may also be used in evaluations of other two-layer systems where reflectance,transmittance and heat transfer properties are known and must be accounted for in the mathematical model. (Author)
