We study the control of coherent light propagation through multiple-scattering media in the presence of measurement noise. In our experiments, we use a two-step optimization procedure to find the optimal incident wavefront that generates a bright focal spot behind the medium. We conclude that the control of coherent light propagation through a multiple-scattering medium is only determined by the number of photoelectrons detected per optimized segment. The prediction of our model agrees well with the experimental results. Our results offer opportunities for imaging applications through scattering media such as biological tissue in the shot noise limit.
我们研究了在存在测量噪声的情况下，相干光通过多重散射介质的传播控制。在我们的实验中，我们使用两步优化程序来找到能在介质后方产生明亮焦斑的最佳入射波前。我们得出结论，相干光通过多重散射介质的传播控制仅由每个优化段检测到的光电子数量决定。我们模型的预测与实验结果吻合良好。我们的结果为在散粒噪声极限下通过诸如生物组织等散射介质进行成像应用提供了机会。
