Coherent Control of Light Transmission hrough Opaque Scattering Media

Wavefront shaping techniques have recently been used to enhance total transmission of light through opaque scattering media such as paper, white paint, or biological tissue. Such enhancement of total transmission relies on the selective coupling of incident light into high-transmission channels. We have studied the properties of such channels, including their spatial profiles and angular correlations.  Our experimental and theoretical results show that coupling light into high-transmission channels not only enhance the total transmission of light, but also provide a wider field of view for imaging applications through opaque scattering media.
