| 摘 要： | 采用Monte Carlo方法和实验,对离散介质表面漫反射光的空间分布进行了研究.结果表明：离散介质表面并非理想朗伯表面;用置换法对整个生物组织漫反射率的平切光纤测量系统进行简单的定标中,把生物组织表面作为朗伯表面处理将使漫反射率计算结果存在偏差,准确的做法应是对漫反射进行空间积分.

| Abstract: | Monte Carlo method is used to analyze the spatial distribution of diffuse reflection light from scattering media irradiated by several common beams of light. A conclusion that the surface of scattering media is not the ideal Lambertian diffuser is obtained and has been confirmed by experiments preliminary. Therefore,the exact method to determine diffuse reflectance of tissue should be a spatial integral to diffuse reflection light from the surface of tissue. |

| Keywords: | scattering media Monte Carlo method diffuse reflectance spatial distribution Lambertian diffuser |
