Strathprints makes available scholarly Open Access content by researchers in the Department of Architecture based within the Faculty of Engineering.

Research activity at Architecture explores a wide variety of significant research areas within architecture and the built environment. Among these is the better exploitation of innovative construction technologies and ICT to optimise 'total building performance', as well as reduce waste and environmental impact. Sustainable architectural and urban design is an important component of this. To this end, the Cluster for Research in Design and Sustainability (CRiDS) focuses its research energies towards developing resilient responses to the social, environmental and economic challenges associated with urbanism and cities, in both the developed and developing world.

Abstract

The influence of the relative intensity noise, in particular the relaxation oscillation noise, of a distributed feedback (DFB) fibre laser on the performance of a polarimetric DFB fibre laser ultrasonic sensor is investigated theoretically and experimentally. A novel demodulation algorithm for the DFB fibre laser ultrasonic sensor is used to demodulate the polarization beat frequency and eliminate the effects of the intensity noise completely. The sensing system is demonstrated to demodulate time varying ultrasonic signals at 2.25 MHz and 10 MHz.
