Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

We review recent developments in optical fiber gas detection using absorption spectroscopy, including open-path gas sensors using fiber coupled micro-optic cells, evanescent wave sensors using D-shaped optical fibers and holey fibers; sensor systems using broadband sources and laser sources; techniques for sensitivity enhancement and noise reduction; and various multi-point gas detection systems.
