Random scattering of light, which takes place in paper, paint and biological tissue is an obstacle to imaging and focusing of light and thus hampers many applications. Propagation of laser light in scattering media can be controlled by shaping the incident wave front using spatial light modulators. Wave front shaping methods in scattering media have given rise to a new wave of fundamental studies of light propagation as well as new modalities of imaging and focusing with scattered light.
In this webinar hosted by the OSA Photonic Detection Technical Group, Dr. Allard Mosk from Universiteit Utrecht will discuss his group’s recent work, which demonstrated that speckle correlations enable non-invasive fluorescence imaging through strongly scattering layers. Scattering “lenses” made of high-index materials allow wide-field speckle-illumination microscopy with a resolution approaching 100 nm. The “Physics of Light in Complex Systems” group led by Dr. Mosk has very recently demonstrated dynamic control of resonant scattering using light, which allows interactive control of scattering, with the possibility to create a new class of adaptive nanophotonic circuits.
What You Will Learn:
Prof. Dr. Allard Mosk obtained his PhD from the University of Amsterdam in 1999. He has done his post-doctoral research in the Max-Planck institute for nuclear physics in Heidelberg and FOM-institute for plasma physics in Rijnhuizen. In 2003 he moved to the University of Twente where he became a Full Professor in 2014. At present, he is the group leader of “Physics of light in complex systems” at Universiteit Utrecht, The Netherlands. He is widely recognized as an innovator in the field of optics in scattering media, having opened the field of wave front shaping in scattering media. Allard is ERC grant holder and a fellow member of the Optical Society (OSA). He has recently received the NWO-VICI grant.
