Open Access research shaping international environmental governance...

Strathprints makes available scholarly Open Access content exploring environmental law and governance, in particular the work of the Strathclyde Centre for Environmental Law & Governance (SCELG) based within the School of Law.

SCELG aims to improve understanding of the trends, challenges and potential solutions across different interconnected areas of environmental law, including capacity-building for sustainable management of biodiversity, oceans, lands and freshwater, as well as for the fight against climate change. The intersection of international, regional, national and local levels of environmental governance, including the customary laws of indigenous peoples and local communities, and legal developments by private actors, is also a signifcant research specialism.

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.
