Abstract

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.
