The method consists of measuring the perturbation provoked by a small volume of the diffusive medium on light propagating through a medium of known optical properties. The absorption and the reduced scattering coefficients of the medium are retrieved from multidistance continuous-wave measurements of transmittance. The inversion procedure is based on the solution of the diffusion equation obtained with a perturbative approach. The method has been validated with Monte Carlo results. Examples of experimental results are reported.
该方法包括测量一小部分扩散介质对在具有已知光学特性的介质中传播的光所引起的扰动。通过对透射率的多距离连续波测量来获取介质的吸收系数和约化散射系数。反演过程基于用微扰方法得到的扩散方程的解。该方法已通过蒙特卡罗结果得到验证。报告了实验结果示例。
