Structural Health Monitoring
The DITEST-SHM (Structural Health Monitoring) system is designed to provide accurate and complete information about actual infrastructure conditions in real-time.
| Fiber optic monitoring of large infrastructures has developed in a complete and innovative Structural Health Monitoring (SHM) strategy which goes beyond the detection of damage occurrence in critical infrastructures such as bridges, dams, buildings, storage tanks, etc. |
Civil engineering - monitoring approach
DITEST-SHM Solution is aiming at providing comprehensive information about the structural health of civil engineering infrastructures and their long term evolution by measuring and mapping temperature and strain variations.

| Crack detection Omnisens DITEST-SHM distributed strain monitoring system now features enhanced signal processing algorithms in order to detect highly localized strain contributions along fiber optic sensors associated to the development of cracks in structures. The crack detection is performed automatically within the spatial resolution of the instrument (0.5m) and cracks in the millimeter range can be efficiently detected. |

Fiber optic sensor selection is key
Various fiber optic sensor designs are available for strain monitoring combining reliability, excellent strain transfer from structure to fiber, strain range and mechanical strength. They are designed for deployment in large infrastructure and are compatible with bonding requirements, direct integration in concrete structures, discrete anchoring points.
