研究了超短光脉冲从散射介质中的时间分辨后向散射在人体皮肤诊断中的潜在应用。介绍了一种基于钛宝石激光的背向散射光记录系统，该系统可以记录深度分辨率为10μm的背向散射光，在与人体皮肤相似的条件下，该系统能够记录最大1 mm深度的散射光。用蒙特卡罗模拟结合详细的实验解释了各种实验参数对后向散射信号的影响。通过这种比较，可以确定作为参考介质的乳胶悬浮液在整体和层状模型结构中的散射特性。
Time-resolved backscattering of ultrashort light pulses from scattering media is investigated with regard to potential application in the diagnosis of human skin. A Ti:sapphire laser based system is presented which allows recording the backscattered light with a depth resolution of 10 μm. Under conditions similar to those of human skin, the system is able to record scattered light from depths of up to 1 mm. Monte-Carlo simulations in combination with detailed experiments are used to explain the influence of various experimental parameters on the backscattering signal. By this comparison, the scattering properties of the latex suspensions used as a reference medium could be determined in bulk and layered model structures.
