Prof. Janis Spigulis, "Activities at the Bio-optics and fibre optics laboratory, University of Latvia"

Abstract

Development of skin optics has opened new possibilities for non-invasive human health assessment. The Bio-optics and fibre optics laboratory at Institute of Atomic Physics and Spectroscopy, University of Latvia, has focused its recent research on following main topics:

• cardio-vascular control by single- and multi-channel skin reflection photoplethysmography (PPG),
• assessment of skin tumors and other pathologies by spectral analysis of laser-excited skin autofluorescence and diffuse reflectance,
• analysis of blood microcirculation features at various depths from the skin surface by a novel technique of multi-spectral PPG

Besides, in collaboration with Latvian optical fibre manufacturers the group develops new optical quality control methods and unconventional designs of the silica-core fibre products, e.g. the side-emitting optical fibres.
