我们报告说，由随机分布的纳米粒子制成的无序介质可以用来克服传统成像系统的衍射极限。提出了一种从混浊介质的多次散射中提取原始图像信息的方法，极大地提高了成像系统的数值孔径。因此，分辨率比衍射极限提高了五倍以上，并且视场扩展到相机的物理区域。我们的技术奠定了基础，使用混浊介质作为远场超透镜。
We report that disordered media made of randomly distributed nanoparticles can be used to overcome the diffraction limit of a conventional imaging system. By developing a method to extract the original image information from the multiple scattering induced by the turbid media, we dramatically increase a numerical aperture of the imaging system. As a result, the the resolution is enhanced by more than five times over the diffraction limit and a field of view is extended over the physical area of the camera. Our technique lays the foundation to use a turbid medium as a far-field superlens.
