论文摘要
散射可以迅速降低我们形成光学图像的能力,以至于只能测量类似斑点的图案。通过强散射障碍物真正的非侵入性成像很困难,通常依赖于计算密集的数值重建。在这项工作中,我们表明,通过在不同时间结合测量斑点模式的互相关,可以以最小的计算工作和大量的视野跟踪移动对象。
Scattering can rapidly degrade our ability to form an optical image, to the point where only speckle-like patterns can be measured. Truly non-invasive imaging through a strongly scattering obstacle is difficult, and usually reliant on a computationally intensive numerical reconstruction. In this work we show that, by combining the cross-correlations of the measured speckle pattern at different times, it is possible to track a moving object with minimal computational effort and over a large field of view.
