摘要
建立了匹配介质的n层半无限厚频域方程的解,并对频域进行傅里叶变换,计算出时域方程的时间分辨漫反射(Time-resolvedReflectance)·为检验漫射模型的准确性,将时间分辨漫反射与蒙特卡罗(MonteCarlo)模拟结果进行了比较,结果表明两者符合得很好·研究表明:该时域漫射模型可以判断生物组织和病变的光学特性·
The solution of the diffuse equations of a n-layered matched medium in frequency domain was set up. Through Fourier transform,the time - resolved reflectance can be computed. In order to test accuracy of the model, the time-resolved reflectance are compared with Monte-Carlo simulation. The results show that the model is described with good accuracy. The research show the optical properties of biological tissue and disease can be determined by the model.
