通过浑浊介质进行高分辨率成像是光学科学的一个基本挑战,近年来由于其广泛的潜在应用而引起了人们的广泛关注。在这里,我们证明了在高散射介质后面的成像系统的分辨率可以在衍射极限以下得到改善。为了实现这一目标,我们展示了一种新的显微镜技术,该技术利用光学记忆效应,使用反卷积图像处理,因此不需要迭代聚焦,扫描或相位恢复过程。我们表明,这种新建立的通过浑浊介质直接成像的能力提供了基本和实用的优势,如三维再聚焦和明确的物体重建。
High-resolution imaging through turbid media is a fundamental challenge of optical sciences that has attracted a lot of attention in recent years for its wide range of potential applications. Here, we demonstrate that the resolution of imaging systems looking behind a highly scattering medium can be improved below the diffraction-limit. To achieve this, we demonstrate a novel microscopy technique enabled by the optical memory effect that uses a deconvolution image processing and thus it does not require iterative focusing, scanning or phase retrieval procedures. We show that this newly established ability of direct imaging through turbid media provides fundamental and practical advantages such as three-dimensional refocusing and unambiguous object reconstruction.
