Optical Instrumentation

Random light beam, such as spontaneously generated through scattering media, is paradoxically very well suited for performing efficient high-resolution compressive imaging. Our efforts both focus on the development of

  • coherent imaging with diffuser-based wavefront sensors
  • super-resolution fluorescence imaging
