Physics of Imaging

Researchers in this group explore the fundamentals of image formation and processing for studying the physical world from the atomic scale through to imaging the human body. Many projects are conducted at major research facilities overseas and locally at Monash University, including the Monash Centre for Electron Microscopy (MCEM) which houses the double aberration corrected Titan TEM, and the Australian Synchrotron, which our X-ray imaging group regularly visits.

Research projects available to students vary widely from theoretical studies of optical vortices and inverse problems to experimental realisation of new imaging modalities.

Ultra-small angle X-ray scattering (USAXS) pattern from the thorax of a mouse reveals micro-structure of the tissues at sub-pixel length scales.
