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

A unique approach to gas detection using optical correlation spectroscopy (OCS) has been investigated. By employing a semiconductor optical amplifier (SOA) with an optical fibre delay line to generate the anti-phase signal, zero point drift errors are minimised and compatibility with single mode optical fibre systems has been achieved. Experimental results, obtained for varying concentrations of acetylene (C2H2) gas at different pressures, agree well with the theoretical analysis. Signal-to-noise ratio (SNR) analysis was also performed to predict the theoretical minimum detectable concentration for C2H2.
