Steering Stable Light Fields Through Dynamic Scattering Media

The scattering of light was once thought to fundamentally limit imaging through opaque samples, as transmitted light becomes spatially scrambled. However, scattering effects can be captured by measurement of the Transmission Matrix (TM) - a linear matrix operator mathematically encapsulating how incident fields will be transformed into new fields on the other side of the scattering medium [1]. Knowledge of a scattering sample's TM enables the scrambling of optical fields to be reversed, and imaging through or inside opaque media becomes possible. Despite these successes, TM-based approaches generally require that the scattering medium remains completely static while the TM is measured and applied. Spatial control of light propagating through dynamic scattering systems remains a very challenging open problem [2], [3].
