Innovative sensor systems based on Interferometry for remote static & dynamic monitoring of structural movements. IBIS microwave interferometry based systems for remote static and dynamic monitoring of bridges and structures such as buildings, historical monuments, towers etc. , to remotely monitor for static applications such as structural load testing, structural displacement and collapse hazards as well as cultural heritage preservation without needing direct access to the site or the use of any invasive equipment. They are also able to perform dynamic monitoring applications including structural resonance frequency measurements, structural modal shape analysis and real time deformation monitoring.
