Advanced Laser Doppler Vibrometers for High-Precision Vibration Testing
Measure structural vibrations without contact using industry-grade Laser Doppler Vibrometers backed by cloud integration and lab-grade accuracy.
Non-Contact Vibration Measurement for Structural Integrity Assessments
Laser Doppler Vibrometers (LDVs) provide highly accurate, non-contact vibration measurements used in testing the dynamic behavior of civil structures. These advanced instruments rely on the Doppler shift of a reflected laser beam to calculate velocity, displacement, and frequency characteristics of vibrating surfaces. This technique ensures precise data acquisition without altering the test subject’s natural behavior—critical for delicate or inaccessible structural components. LDVs are widely used in modal analysis, resonance studies, and condition monitoring of bridges, buildings, tunnels, and transportation infrastructure.
As a trusted provider of structural testing technologies, Civil Structure Test Tech supports North American B2B customers with LDV solutions designed to integrate seamlessly into lab and field testing environments.
Our offerings span single-point and scanning LDVs, coupled with compatible software platforms and data handling services.

Case Studies
United States: Bridge Resonance Monitoring in Ohio
A municipal transportation authority used LDVs to monitor resonance in aging steel truss bridges during rush-hour load conditions. The system identified frequency shifts indicating early-stage fatigue, enabling preemptive reinforcement.
United States: Seismic Simulation at a California Research Lab
Researchers at a structural testing facility integrated scanning LDVs into a full-scale seismic simulation of a mid-rise building. Real-time displacement and velocity readings enhanced model correlation during induced shaking.
Canada: Light Rail Structure Testing in Ottawa
A civil engineering firm conducted dynamic testing on elevated rail infrastructure using LDVs to assess structural behavior under train-induced vibration. The non-contact nature minimized setup time on active lines.
