| Abstract: | The terrestrial microwave interferometry is a rather new
measuring technique, which allows the measurement of relative
displacements of structures with an accuracy of up to 0.01 mm at a sampling
rate of up to 4000 Hz, without any kind of instrumentation on the structure.
Due to the high sampling frequency, capturing the vibrational behaviour of
the measured object is also possible and thus its modal parameters can be
directly determined. This paper presents briefly the measuring principle and
some preliminary investigations performed to demonstrate the applicability
of this measuring technique in structural dynamics of bridges. |
