Retinal Imaging
Spectral imaging of the retina enables non-invasive mapping of retinal chemicals; such as oxy- and deoxy-hemoglobin; that are of great interest in understanding eye metabolic processes and for the detection and screening for retinal disease. We conduct research into the development of instrumentation for spectral retinal imaging and into algorithms for inverting the data contained in in these spectral images to yield quantified chemical maps. This involves the development of a rigorous understanding of the physics of light propagation in the retina and Monte-Carlo modelling combined with analytical physical models.
