Abstract

This paper presents the development of a high precision three-dimensional measurement system using laser doppler vibrometers. Two measurement systems were developed. Then, the following fundamental issues were studied and the results presented: measurement principle, accuracy with respect to long distance measurements and laser beam angles. As examples of possible applications of the system, measurements of ground motion, measurement of wave propagation in a plate and vibration measurement of a steel railway bridge were treated.
