标题： Characterization of the angular memory effect of scattered light in biological tissues

摘要： 高分辨率光学显微镜在神经科学中是必不可少的，但会受到生物组织中的散射影响。因此，它只能访问表层。最近开发的技术通过利用透射光中的角度相关性来使用散射光子进行成像，有可能增加成像深度。但这些相关性（“角度记忆效应”）范围非常短，在理论上仅存在于散射介质之后而非内部。通过在神经组织上的测量和补充模拟，我们发现生物组织中的强前向散射可以使记忆效应范围（从而可能的视场）比各向同性散射在$\sim$1毫米厚的组织层中增强一个数量级以上。 显示英文摘要

摘要： High resolution optical microscopy is essential in neuroscience but suffers from scattering in biological tissues. It therefore grants access to superficial layers only. Recently developed techniques use scattered photons for imaging by exploiting angular correlations in transmitted light and could potentially increase imaging depths. But those correlations (`angular memory effect') are of very short range and, in theory, only present behind and not inside scattering media. From measurements on neural tissues and complementary simulations, we find that strong forward scattering in biological tissues can enhance the memory effect range (and thus the possible field-of-view) by more than an order of magnitude compared to isotropic scattering for $\sim$1\,mm thick tissue layers.
