Singular optics & random media

Singular optics & random media

Smart light-beam manipulation through biological tissues can be achieved by exploiting the correlation properties in their transmission matrix. In our works, we mostly focused upon

  • Topological correlations in the random speckle fields generated by diffusers
  • Spectral correlation properties of forward scattering media

These fundamental studies are the corner stones for the development of novel imaging capabilities.
