论文摘要
传输矩阵（TM）是通过散射介质描述光散射过程的表示。 TM中的控制元素的程度与评估大量不知道参数的巨大方程的能力相关，这些方程严重限制了TM的效率和准确性，因此进一步限制了诸如图像恢复之类的应用。为了完全消除这一限制，我们提出分解TM并顺序获取尺寸减少了分解，涉及散射介质后面传输场的时间和空间不变性性质。这种提出的方法不仅具有实现具有完全可控元素的高维传输矩阵的能力，而且还可以在评估过程中带来优化的信噪比，这为研究人员提供了一种达到最大焦点效率或图像重建分辨率的方法。
The transmission matrix (TM) is a representation to describe the light scattering process through a scattering medium. The degree of control elements in TM is correlated with the capacity of evaluating enormous equations with tremendous number of unknow parameters, which seriously restricts the efficiency and accuracy of TM, and thus further confines applications such as image recovery. To completely remove this restriction, we propose decomposing TM and sequentially acquiring the dimension reduced decompositions regarding to the time and space invariance nature of transmitted field behind scattering medium. This proposed approach would not only have the ability to achieve high dimension transmission matrix with fully controllable elements, but also brings optimized signal-to-noise ratio during evaluation processing, which provides researchers a way to reach maximal focusing efficiency or image reconstruction resolution.
