N2 - In this thesis, we explored the use of wavefront shaping to steer light through strongly scattering materials. We found that scattering does not irreversibly scramble the incidentwave. By shaping the incident wavefront, an opaque object can formany desired wavefront and focus light as sharply as an aberration free lens. We used feedback from a target behind, or in, an opaque object to shape the incident wave. This way, light was focused through, or inside, an opaque object for the first time ever. Wavefront shaping provides a newway to performexperiments on strongly scattering samples. By studying the total intensity transmission of a shaped wavefront, we found experimental evidence of open transport channels for light. This is an example of how wavefront shaping can be used to study fundamental properties of scattered waves.
