摘要：

A time-gated technique to enhance viewing through highly scattering media such as tissue is discussed. Experiments have been performed on tissue like plastic phantoms to determine the possibilities and limitations of the technique. The effects of the time-gate width and the localization, size, and optical properties of hidden objects have been studied. A computer model to simulate light propagation in tissue is also presented. The predictions of the model are compared with experimental results. (C) 1996 Optical Society ofAmerica
