LiDAR Technology for Structural Dynamics

OMMATIDIA'S LIDAR TECHNOLOGY Ommatidia's Q1 system generates 128 laser beams, enabling local measurement of sub-millimetre displacements and real-time vibration analysis of large structures. These beams function as non-contact gauges and precision accelerometers. Precise characterisation of structural deflection under load. LiDAR provides high-sensitivity vibration data at the points where the light is projected. What are the advantages? Ommatidia's multibeam LiDAR technology offers multiple advantages in the field of civil engineering: Dynamic and Structural Characterisation Simplified Continuous...

STRUCTURAL DYNAMICS APPLICATIONS By treating each light beam as an accelerometer, LiDAR provides detailed insights into the vibrations and movements of structures in real-time. The Ommatidia Q1 system, with its 128beam capability, offers a robust platform for structural analysis. 3D dynamic characterization of structures and vibrations measurement. Operational Modal Analysis (OMA) Structural health monitoring (SHM) Velocity Measurement The Doppler effect causes a frequency shift, and dual laser slopes separate distance and velocity, resulting in precise velocity measurement (λ = 1550 nm). The...

Q1S: ADVANCED MEASUREMENT CAPABILITIES The Q1S, a variant of the original Q1, focuses on measuring local deflection and vibrations in large civil structures. Special algorithms enhance the unit's sensitivity, allowing for operational modal analysis based on ambient excitation. The Q1S simplifies fixed installation in various infrastructure types, and with its IP54 protection, it is suitable for long-term outdoor operation. This robust construction also enables cost-efficient deployment. Deployment and Applications Installed Q1S for continuous structural health monitoring can gather detailed information...
