Unrivalled system performance
The OSMOS surveillance system is based on the principle of intensity modulation using analogue measurement, a procedure selected only after all other fiber optic procedures for examining changes in position and form had been thoroughly tested. This is a proven technology which not only enables stable and reliable solutions but also operates with minimal electronic and mechanical components. With this system, OSMOS offers the only surveillance system of its kind world-wide, a system based on the simultaneous recording of dynamic and static data with a high level of precision – a successful translation of basic research into applications technology.

Innovative technology for practical use |

The principle of Optical Strands
If a fiber optic cable is bent, it loses some of its light where the bending takes place. With the aid of light attenuation measurements, this loss can be measured with high precision. The sensor effect is based on the correlation between the changes in attenuation, or light intensity, on the one hand and changes in the length of the fiber optic cable on the other. |

OSMOS measurement system: reliable, precise and cost-effective
OSMOS sensors do not simply record possible structural deformations at specific points; instead, they record these across a longer distance representative of the geometry of the structure involved. In this way, a single sensor can measure any changes which take place across a range of up to 10 meters. This is why even large-scale structures can be monitored reliably with relatively few sensors – contributing, in turn, to a favorable cost structure. The signal measuring instruments themselves are easy to install and practically maintenance-free. |
Optoelectronics and signal processing
An optoelectronic receiver, the so-called Opto-Box, provides precise recording of the signals transmitted by the fiber-optic sensors. The electrical signals coming from the Opto-Box are evaluated and passed along via modem. The compact system components operate absolutely free of malfunction. |
