介绍了一种光学方法，用于观察时间和空间分辨的帧，显示光如何在漫散射材料中传播。该方法允许在时间上产生具有100-fs分辨率的视频。该方法利用短相干干涉法。信息的来源是散斑对比度。多次散射过程的时间和空间演变的几个生物和工业样品证明。该方法的一个主要目的是研究在短相干干涉测量中实现高分辨率的最佳相干性和最佳孔径的条件。一个重要的结果是，在传播过程中，一个尖锐的光子视界的演变，这是有用的体散射体的形态分析。(C)1996年美国光学学会
An optical method is introduced for observation of temporally and spatially resolved frames that show how light propagates in diffusely scattering materials. The method permits videos with 100-fs resolution in time to be produced. The method utilizes short-coherence interferometry. The source of information is the speckle contrast. The temporal and spatial evolution of the multiple scattering process is demonstrated for several biological and industrial samples. A major objective of the method is to investigate the conditions for optimum coherence and optimum apertures to achieve high resolution in the short-coherence interferometry. One important result is that during the propagation a sharp photon horizon evolves, which is useful for the morphological analysis of volume scatterers. (C) 1996 Optical Society of America
