eneral description of the IBIS-S system
The IBIS-S system is designed to remotely measure displacements with a sampling
frequency up to 200 Hz with an accuracy as fine as a hundredth of a millimetre.
The performance of the IBIS-S system depends on the type of configuration used and on
the operative measurement conditions; however, the best performance characteristics can
be defined as follows:
• Maximum operational distance: 1000 m;
• Maximum image resolution in distance: 75 cm;
• Accuracy in measuring displacements in the viewing direction: 0.01 mm;
The time required for instrument installation is about 20 minutes, and the same time is
required for its dismantling.
The instrument has been specifically designed for outdoor use and is equipped with IP65
level protection and is supplied with a notebook PC specifically designed for outdoor use
in extreme conditions.
The IBIS-S system offers the following advantages over currently available monitoring
systems (GPS, extensometers, accelerometers ):
• remote monitoring without the need to access the structure to be monitored
• Resolution of 0.75 m which permits IBIS-S to identify a large number of “virtual
displacement sensors” on the area under investigation, simply by remotely
targeting the scenario;
• Acquisition frequency of the entire measurement area up to 200Hz;
• Directly measure the displacements in real time: IBIS-S can process acquired data
and display the displacement of a point selected from the scenario in real time.
This IBIS-S characteristic permits the monitoring of damaged structures with real
time generation of alarm signals in case of collapse danger;
