With background in atomic spectroscopy, optoelectronics and fibre optics, over the last decade I am mostly involved in biophotonics research. We develop novel optical methods and devices for non-invasive diagnostics and monitoring of human health condition. Spectral, temporal and imaging analysis of optical signals from in-vivo skin may ensure quantitave assessment of cardio-vascular state, skin blood micro-circulation, skin pigmentation and various skin malformations. The techniques developed in laboratory and evaluated in clinical studies are photoplethysmography (PPG), fluorescence, diffuse reflectance spectroscopy and multi-spectral imaging. The expected outcomes of our research are advanced clinical technologies, such as:
ü Fast detection of leg stenosis by bilateral PPG;
ü Remote cardiovascular monitoring by embedded wireless PPG sensors;
ü Remote skin blood perfusion control during anaesthesia by PPG imaging;
ü Remote skin chromophore mapping by multi-spectral imaging analysis;
ü Remote skin melanoma detection by chromophore correlation analysis and parametric imaging;
ü Improved skin laser safety standards with respect to skin “photo-memory” at low power irradiation.
The recent developments in these areas are reviewed here.
