光学成像依赖于照亮物体、收集和分析其散射或传输的光的能力。到目前为止，通过生物组织等复杂介质的传播被认为由于多次散射而降低了可获得的深度和成像的分辨率。这就是为什么这类媒体通常被认为是不透明的。最近，我们证明了测量复杂的介观光学传输通道是可能的，这些通道允许光穿过这样一个不透明的介质。在这里，我们表明，我们可以最优地利用这些通道来相干地传输和恢复高保真的任意图像，而与传播的复杂性无关。
Optical imaging relies on the ability to illuminate an object, collect and analyse the light it scatters or transmits. Propagation through complex media such as biological tissues was so far believed to degrade the attainable depth, as well as the resolution for imaging, because of multiple scattering. This is why such media are usually considered opaque. Recently, we demonstrated that it is possible to measure the complex mesoscopic optical transmission channels that allow light to traverse through such an opaque medium. Here, we show that we can optimally exploit those channels to coherently transmit and recover an arbitrary image with a high fidelity, independently of the complexity of the propagation.
