Automotive NVH testing
Full-field automotive NVH testing without contact sensors
Measure vibration across vehicle bodies, panels, glazing, tires, doors, trims, and subassemblies without adding accelerometers, wiring, or sensor mass.
Ommatidia Q2 combines dense optical vibrometry with 3D geometry, helping NVH teams see response patterns directly on the measured surface.

Why teams move beyond contact-heavy setups
Reduce setup burden without losing spatial detail
Traditional accelerometer layouts can add mass, change the behavior of lightweight structures, and slow down prototype or validation work through mounting, cabling, and channel checks.
- Preserve dynamic boundary conditions by measuring without contact.
- Reduce installation time and cabling complexity.
- Identify which panels and subassemblies respond at each frequency.
- Support ODS review, FEM correlation, and faster design comparison.
What Q2 changes in NVH testing
Full-field data with less instrumentation effort
- Quantitative vibration measurements in physical velocity units.
- High spatial density for localized source and response detection.
- Fast deployment with less fixture and cable preparation.
- Usable across lab and field validation setups.
- Portable between prototypes, test rigs, and measurement campaigns.
Car Body Vibration application note
Vehicle-scale vibration data on measured geometry
Use one optical head to capture surface geometry and vibration response, then review the NVH behavior directly on the measured vehicle surface instead of stitching separate scans and sensor layouts together.
- One non-contact setup for body, tire, door, and trim response.
- Dense line-based acquisition for full-field interpretation.
- Geometry-aware results that make modal analysis and ODS review easier to communicate.

Why Q2 fits automotive NVH
Dense spatial coverage with geometry context
Q2 captures multiple points per line and links vibration data to measured geometry, helping teams move from test setup to engineering interpretation with fewer toolchain handoffs.
Practical on real vehicle surfaces
The car-body measurement work includes dark body and tire surfaces, a practical requirement for validation environments where reflectivity and surface finish vary across the vehicle.
For platform selection across single-point LDV, portable Laser RADAR, and dense 3D vibrometry, use the Q-Series comparison guide.
Proof from real vehicle measurements
Body vibration mapped across the vehicle
Full-field body vibration mapping from 65 simultaneous points per line, with response visualized directly on the vehicle geometry.
One optical head for geometry and dynamics
Q2 combines 3D surface measurement and vibration data, so NVH teams can relate velocity, displacement, and strain-ready fields to measured vehicle geometry without running a separate scan.

Next step
Check fit for your NVH test setup
If you are planning body, panel, trim, glazing, tire, or subassembly tests, we can review target size, stand-off distance, excitation method, and required outputs.
Plan a focused technical review
Bring your vehicle structure, range, setup, and analysis objectives. We will help identify whether Q2 is the right route for denser full-field vibration insight with less instrumentation burden.
