Recently the optical transmission matrix (TM) has been shown to be useful in controlling the propagation of light in highly scattering media. In this paper, we present the vector transmission matrix (VTM) which, unlike the TM, captures both the intensity and polarization transmission property of the scattering medium. We present an experimental technique for measuring the absolute values of the VTM elements which is in contrast to existing techniques whereby the TM elements are measured to within a scaling factor. The usefulness of the VTM is illustrated by showing that it can be used to both predict and control the magnitude of the complex polarization ratio of the light focused through the scattering medium. To the best of our knowledge, this is the first study to show the possibility of controlling the polarization of the light transmitted through highly scattering media.
最近，光学传输矩阵（TM）已被证明在控制光在高散射介质中的传播方面很有用。在本文中，我们提出了矢量传输矩阵（VTM），与TM不同，它能捕捉散射介质的强度和偏振传输特性。我们提出了一种测量VTM元素绝对值的实验技术，这与现有技术不同，现有技术只能将TM元素测量到一个比例因子范围内。通过表明VTM可用于预测和控制通过散射介质聚焦的光的复偏振比的大小，说明了VTM的实用性。据我们所知，这是第一项表明控制通过高散射介质传输的光的偏振可能性的研究。
