Laser Doppler Vibrometer Systems for Remote NVH and Modal Testing
Capture NVH, modal and structural-dynamics data remotely with laser Doppler vibrometry—using 65 or 128 simultaneous measurement points—without placing contact sensors, routing dense wiring or adding mass to lightweight targets. Ommatidia combines Q-Series Laser RADAR systems with practical test workflows for difficult and access-constrained targets.
Capture vibration data with less setup
Contact vibration testing requires a sensor to be mounted, wired, and prepared at every measurement point. Remote laser vibrometry captures many points from a distance, reducing setup effort while preserving the target’s natural response. Explore laser vibrometry fundamentals.
Parallel 65- or 128-point capture moves teams from setup to full-field vibration insight with fewer bottlenecks—helping NVH and modal campaigns reach useful decisions faster.

How the measurement workflow works
1. Define the target
Clarify the structure, operating condition, and measurement objective.
2. Capture remotely
Acquire vibration data without contact instrumentation burden.
3. Review the data
Interpret results for NVH, modal, or structural analysis.
4. Decide next steps
Use findings to accelerate engineering decisions and test planning.
Common use cases
Use this page to decide whether Ommatidia should be part of your next technical evaluation for vibration, NVH or modal testing. Compare Laser RADAR and scanning LDV when the method is not yet fixed, then review the vibrometry and inspection application briefs for deeper examples.
Automotive NVH
Capture full-field body-panel, glazing, trim, and subassembly response without dense accelerometer wiring or added mass.
Modal testing
Capture mode shapes, spectra, and spatial response with less point-by-point scanning and preparation.
R&D validation workflows
Evaluate difficult, lightweight, hot, or access-constrained targets without changing the test with contact instrumentation.
Plan your remote vibrometry measurement
Remote laser vibrometry captures surface velocity without mounting a sensor at every point. Parallel Q-Series Laser RADAR adds dense spatial coverage with less cabling and added mass; accelerometers provide complementary reference or trigger signals.
Ommatidia develops Q2 measurement workflows for low-reflectivity and hard-to-access components. The team matches the optical geometry, working distance and acquisition to the surface and motion you want to study.
Remote vibrometry supports automotive NVH, modal testing, operating-deflection-shape analysis, rotating and lightweight components, and structural dynamics. Simultaneous optical measurements connect the spatial vibration response to the engineering decision.
Share the component and the engineering question you want to answer. Ommatidia’s applications team outlines the measurement approach, useful data outputs and the next practical step.
Start with the target, working distance, vibration bandwidth and desired coverage. Add the operating condition, reference or trigger requirements and data format so the campaign delivers the information your analysis needs.
Arrange a demonstration or focused measurement campaign using a representative component. Review vibration maps, geometric context, synchronized signals and data exports with Ommatidia’s applications team to choose your Q-Series configuration.
