The strong optical scattering of biological tissue confounds our ability to focus light deeply
into the brain beyond depths of a few hundred microns. This challenge can be potentially
overcome by exploiting wavefront shaping techniques which allow light to be focused
through or inside scattering media. However, these techniques require the scattering
medium to be static, as changes in the arrangement of the scatterers between the wavefront
recording and playback steps reduce the fidelity of the focus that is formed. Furthermore, as …
