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.
光学成像是基于对物体进行照明、收集和分析其散射或传输光的能力。由于多次散射，光在复杂介质（如生物组织）中的传播一直被认为会降低可达到的深度和成像分辨率。这就是为什么此类介质通常被认为是不透明的。最近，我们证明了可以测量复杂的介观光学传输通道，这些通道允许光穿过这种不透明介质。在这里，我们表明可以通过最佳利用这些通道，以高保真度相干地传输和恢复任意图像，而与传播的复杂性无关。
