介绍了一种实验测量复杂介质光学单色传输矩阵的方法。该方法基于空间位相调制器和相机上的全场干涉测量。我们确定了厚随机散射样品的传输矩阵。结果表明，该矩阵表现出与随机矩阵理论相一致的统计性质，并允许光聚焦和成像通过随机介质。这种方法可能会对复杂介质的介观性质提供重要的见解。
We introduce a method to experimentally measure the monochromatic transmission matrix of a complex medium in optics. This method is based on a spatial phase modulator together with a full-field interferometric measurement on a camera. We determine the transmission matrix of a thick random scattering sample. We show that this matrix exhibits statistical properties in good agreement with random matrix theory and allows light focusing and imaging through the random medium. This method might give important insight into the mesoscopic properties of a complex medium.
