Optical imaging
IRL’s optical imaging research is focussed on the industrial and biomedical application of optical techniques, including optical coherence tomography and laser speckle contrast imaging.

The scope of our research includes both the development and application of optical measurements. A strong focus on understanding the physical basis of optical techniques underpins our work and allows both new approaches and better analysis and interpretation of older techniques.
Current research projects include constructing a biomedical optical coherence tomography system. This will use a novel range scanner to extract optical properties of tissue, measuring dermal perfusion using laser speckle contrast analysis, with an improved measurement procedure and algorithm to yield quantitative data, and extending the scope of the speckle technique to measure flow in the small blood vessels of the retina.
