Revolutionizing Structural Health Monitoring with Laser Radar Technology
The Q1S Laser RADAR system is a cutting-edge tool developed for structural health monitoring (SHM) that is revolutionizing the field of civil engineering. To that end, this innovative solution combines high-precision vibration testing with advanced deflection and displacement measurements, providing unparalleled insights into the health and stability of large civil structures.
Powered by state-of-the-art infrared (NIR) laser technology, the Q1S delivers precise 3D data, thus enabling engineers to perform operational modal analysis and long-term surveying of critical infrastructures such as bridges, tunnels, or buildings.
Superior Accuracy and Efficiency for Infrastructure Surveying
The Q1S stands out because of its advanced interferometric capabilities, enabling precise deflection and vibration measurements across various infrastructure types. Moreover, its 128 parallel laser beams provide metrology accuracy, resolving surface coordinates to within tens of microns and deflections below one micron.
Unlike traditional tools such as total stations, the Q1S not only eliminates the need for markers or surface changes but also accelerates data collection, thereby improving efficiency overall.
Key Features of Q1S for Civil Infrastructure

Q1S Laser RADAR for Structural Health Monitoring
-
Bridges and Overpasses: Bridges, as critical parts of transportation networks, face dynamic loads, aging, and environmental stress. Consequently, the Q1S provides real-time deflection and vibrometry data, ensuring both structural integrity and public safety. Moreover, its precise measurements allow for early detection of risks.
-
Skyscrapers and High-Rise Buildings: As urbanization grows, surveying the dynamic behavior of tall buildings during seismic events or wind loads becomes vital. Not only does the Q1S enable engineers to assess resilience, but it also helps optimize designs to mitigate risks and improve safety.
-
Tunnels and Underground Structures: Underground infrastructures often experience ground movement and subsidence. Accordingly, the Q1S’s precise laser measuring tools detect potential issues early. As a result, timely interventions become possible, reducing risks significantly.
-
Dams and Water Infrastructure: Large-scale water management structures face unique challenges. With its ability to monitor vibrations and shifts, the Q1S ensures long-term stability. Additionally, it helps prevent catastrophic failures by identifying problems before they escalate.
Ease of Deployment
Designed with IP54-rated protection, the Q1S is a surveying equipment that is suitable for outdoor, long-term use. Its lightweight design ensures portability and easy integration into existing total station workflows.
Cost-Effective Maintenance
By identifying issues early, the Q1S minimizes costly repairs and extends the operational lifespan of infrastructure.

Enhanced Safety
The Q1S is a laser measure system with the ability to detect subtle changes in structural dynamics. In turn, this helps prevent structural failures, protecting lives and property.
Comparative Advantages
High-precision laser radar integrates seamlessly, enabling fast, non-destructive testing for Digital Twin ecosystems.
Precision and Speed
The Q1S collects optical metrology data from 128 Laser Vibrometer beams simultaneously, surpassing traditional tools like strain gauges in measurement points, installation speed and accuracy. Thanks to its single-location deployment, setup and maintenance is greatly simplified.
Seamless Integration
In addition, the system integrates with other sensor technologies, such as accelerometers, strain gauges or distance sensors, with an internal GPS clock for synchronization. It is consequently a complete solution for monitoring and maintaining infrastructure. This adaptability aligns with the principles of Digital Twin ecosystems.
Non-Destructive Testing (NDT)
Finally, the Q1S supports non-contact, non-destructive testing methods, preserving the integrity of the structures while providing detailed insights. Particularly, this ability to measure remotely is valuable when monitoring historical sites and constructions, where installation of accelerometers, strain gauges or distance sensors, may not be possible or desirable.
