This paper describes a non-contact vibration measuring system that is based on a microwave interferometer similar to those used to detect the presence of people in monitored areas. Displacement response of a target surface on the structure relative to the interferometer is measured by analysing the

Abstract
In this paper, the authors propose continuousโwave singleโfrequency (CWโSF) and multiโfrequency (CWโMF) microwave techniques for measurement of largeโstructure vibration. Theoretical background and experimental results of tests on a vertical steel structure, subjected both to artificial solicitation through a vibrodyne and to wind, are reported. ยฉ 2003 Wiley Periodicals, Inc.
