Giant fluctuations of focused light reveal hidden correlations in opaque materials

When light travels through a strongly scattering material, such as biological tissue or other disordered opaque media, it follows many different paths and produces a seemingly random speckle pattern. Wavefront shaping makes it possible to control this complex interference and focus light through such materials.

Light scattering through opaque materials, including biological tissue and other disordered media, creates a seemingly random speckle pattern as waves travel along many paths. Wavefront shaping can control the complex interference and focus light through the material.
Researchers say giant fluctuations in the focused light reveal hidden correlations in these materials.
