AI Insight
Researchers have discovered that when light passes through strongly scattering materials like biological tissue, the resulting speckle patterns contain hidden correlations that can be exploited. Using wavefront shaping techniques, scientists can control the complex interference patterns to focus light through opaque materials. The giant fluctuations observed in focused light reveal previously unknown correlations within disordered media.
Why it matters
This research could enable better imaging techniques for medical diagnostics, allowing doctors to see through tissue more effectively. The ability to focus light through opaque materials has applications in optical communications, microscopy, and potentially treating diseases deep within the body.
Understand the Science
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.
