About Super-depth Imaging Lab
 

Our lab has been a part of the Center for Molecular Spectroscopy and Dynamics, Institute for Basic Science in Korea since July 1, 2016. It also belongs to the Department of Physics, Korea University. The labs are located at the R&D center and Asan Science building, both in Korea University Seoul campus.

The laboratory aims to develop optical methodologies for imaging, sensing, and light manipulation of targets located deep within scattering media with their working depth beyond the level of conventional approaches. In particular, we are determined to solve inverse scattering problems at the microscopic level of scattering events and understand the physics of wave propagation inside scattering media. At the same time, we are expanding our studies to apply the developed methods for important biological and biomedical problems.
