最近已经利用了几种现象来规避散射，并且已经成功地使光通过混浊层成像或聚焦。然而，在成像过程期间对混浊介质的稳定的要求仍然是这些方法的基本限制。在这里，我们介绍了一种光学成像模式，克服了这一挑战，利用所谓的窗帘效应，适应于空间频率域通过散斑相关。我们提出了隐藏在毫米厚组织或致密透镜白内障后面的物体的高分辨率成像。我们证明了我们的成像技术对超出任何生物相关运动的快速介质运动（> 5 m/s）不敏感。此外，我们表明这种方法可以扩展到几个对比度机制和成像配置。
Several phenomena have been recently exploited to circumvent scattering and have succeeded in imaging or focusing light through turbid layers. However, the requirement for the turbid medium to be steady during the imaging process remains a fundamental limitation of these methods. Here we introduce an optical imaging modality that overcomes this challenge by taking advantage of the so-called shower-curtain effect, adapted to the spatial-frequency domain via speckle correlography. We present high resolution imaging of objects hidden behind millimeter-thick tissue or dense lens cataracts. We demonstrate our imaging technique to be insensitive to rapid medium movements (> 5 m/s) beyond any biologically-relevant motion. Furthermore, we show this method can be extended to several contrast mechanisms and imaging configurations.
