摘　　要：应用于皮肤微循环测量的激光多普勒血流计的原理是多普勒频移和非多普勒频移后向散射光的干涉．采用蒙特卡罗方法模拟光在皮肤内血流循环中的传播模式，研究光子在坐标轴原点和检测器之间距离的分布．The principle of laser Doppler blood flowmetry applied for skin perfusion measurements is based on the interference of Doppler-shifted and non-Doppler-shifed backscattered light. Light propagation in a model for blood perfusion in dermis was simulated with Monte Carlo calculations to investigated the distribution of photons on the distance between the origin of a coordinate axis and the detector.
