Brillouin Confocal Microscopy

The mechanical properties of biological tissues and biomaterials are closely related to their functional abilities; thus, measuring such mechanical properties non-invasively, in vivo, with micron-scale resolution, would have a wide range of biomedical applications.  We are exploring an all-optical approach to this problem based on Brillouin light scattering.  In Brillouin scattering, the interaction between incident photons and acoustic phonons inside a material leads to a tiny frequency shift in the scattered light.  To measure such frequency shift, we have developed a high-resolution optical spectrometer with unprecedented detection efficiency.  In addition, we have integrated the spectrometer with a home-built confocal microscope to allow the formation of images that use elastic properties as contrast mechanism.

Giuliano Scarcelli 

Giuliano Scarcelli obtained his Ph.D. in physics from the University of Maryland, Baltimore County and the University of Bari, Italy.  His graduate studies, in quantum optics, were dedicated to studying correlated and entangled photons and their applications for imaging and metrology protocols.  After graduation, Giuliano left Maryland for Boston where he joined the Wellman Center for Photomedicine, namely the in vivo microscopy group of Prof. Yun, to develop novel microscopy techniques for biomedical applications.
