Non-invasive Focusing Through Scattering Layers Using Speckle-Correlations
arXiv:1808.03267 · doi:10.1364/OL.44.000143
Abstract
Angular speckle correlations known as the 'memory-effect' have recently been exploited for non-invasive imaging through scattering layers. Here, we show how the imaging information obtained from speckle correlations can be used as a noninvasive feedback mechanism for wavefront shaping. We utilize this feedback to demonstrate guide-star free noninvasive focusing of coherent light through highly scattering layers.
