OCT is an interferometric technique that allows high resolution in vivo, non-invasive imaging of human tissues. Such a system uses the coherence properties of a light source to map biological tissues in 3 dimensions. If the light source is sufficiently incoherent, details as small as a few microns can be resolved, i.e., a few cells, and it is possible to scan up to a few millimetres in the depth of the tissue under investigation without having to cut or even to touch it. Over the past few years, we have been working on investigating different aspects of OCT like dispersion, polarisation and speckle. We have also a particular interest in new sources and we have recently developed sources with unprecedented coherence length allowing for deeper imaging. We are also working on pushing the limits of OCT in terms of tissue differentiation using new contrast mechanisms.
Our most recent goal is to develop the technology for optical biopsies funded by a successful RSNZ Marsden grant.
We are also developing interests in the cartilage area.
