Optical coherence tomography

OCT uses the coherence properties of a light source to map biological tissues in three dimensions.


If the light source is sufficiently incoherent, details as small as a few cells can be resolved. It is also possible to scan up to a few millimetres in the depth of a tissue under investigation without having to cut or even touch it.

Research includes:

  • Different aspects of OCT like dispersion, polarisation and speckle

  • New sources and sources with unprecedented coherence length allowing for deeper imaging

  • Pushing the limits of OCT in terms of tissue differentiation using new contrast mechanisms

  • Cartilage study

  • Developing the technology for optical biopsies funded by an RSNZ Marsden grant.
