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
