Angular speckle correlations known as the "memory effect" have recently been exploited for noninvasive imaging through scattering layers. Here we show that the information obtained from speckle correlations can be used as a noninvasive feedback mechanism for wavefront shaping. We utilize this feedback to demonstrate noninvasive diffraction-limited focusing of coherent light through thin scattering layers.
角散斑相关，也称为“记忆效应”，最近已被用于通过散射层进行非侵入性成像。在这里，我们展示了从散斑相关中获得的信息可以用作波前整形的非侵入性反馈机制。我们利用这种反馈来演示相干光通过薄散射层的非侵入性衍射受限聚焦。
