The optical memory effect has emerged as a powerful tool for imaging through multiple-scattering media; however, the finite angular range of the memory effect limits the field of view. Here, we demonstrate experimentally that selective coupling of incident light into a high-transmission channel increases the angular memory-effect range. This enhancement is attributed to the robustness of the high-transmission channels against perturbations such as sample tilt or wave front tilt. Our work shows that the high-transmission channels provide an enhanced field of view for memory-effect-based imaging through diffusive media.
光学记忆效应已成为穿透多散射介质成像的有力工具；然而，记忆效应的有限角范围限制了视场。在这里，我们通过实验证明，选择性地将入射光耦合到高透过率通道中可以增加角度记忆效应范围。这种增强归因于高透过率通道对样品倾斜或波前倾斜等扰动的鲁棒性。我们的工作表明，高透过率通道为基于记忆效应的扩散介质成像提供了增强的视场。
