Abstract

The spatial structure of optically heterogeneous turbid media is probed with diffusive light. Projection images are obtained experimentally by deconvolution of the scattered diffuse-photon density waves on a planar boundary by use of a fast Fourier transform. The method is very fast, permitting object localization and characterization in ~1000 volume-element samples on subsecond computational time scales. The optical properties of slice-shape inhomogeneities are accurately determined.

摘要

利用漫射光探测光学非均匀浑浊介质的空间结构。通过使用快速傅里叶变换对平面边界上散射的漫射光子密度波进行反卷积，实验获得投影图像。该方法速度非常快，能够在亚秒级的计算时间尺度上对约1000个体积元样本进行目标定位和表征。可以精确确定切片状不均匀性的光学特性。
