Giant fluctuations of focused light reveal hidden correlations
Researchers have discovered that giant fluctuations in focused light can be used to uncover hidden correlations within opaque, scattering materials. By analyzing the complex speckle patterns produced when light passes through disordered media, scientists can gain deeper insights into the internal structure of these substances. This breakthrough leverages wavefront shaping techniques to control light interference. The ability to map these correlations opens new possibilities for non-invasive imaging in biological tissues and other complex materials.
