Affordable Single-Beam LDV for High-Speed, High-Frequency and Long-Range Measurements
For many vibration measurement tasks, you need a system that is fast to deploy, easy to read out, allows high speeds and high frequencies, and is affordable enough to fit your budget.
QMini is Ommatidia’s single-beam laser vibrometer readout station for single-point measurement setups.
Combined with SpeedSync, it delivers a high-speed, high-dynamic-range, affordable single-beam LDV solution for uncompromising users who want practical non-contact vibration measurement for fast moving objects and long ranges without the complexity of a larger system.
A practical LDV solution for single-point measurements
QMini is designed for engineers and test teams who need a simple high-performance way to capture vibration data from a single location on a structure or component. It is ideal where one high-quality measurement point is enough to validate performance, compare conditions, or monitor a critical response.
This makes QMini especially suitable for:
- Entry-level laser Doppler vibrometry
- Single-point vibration measurement
- Bench testing and lab setups
- Educational and R&D environments
- Cost-sensitive industrial diagnostics
- First-step adoption of non-contact vibration measurement
Instead of building a full multi-point workflow from day one, users can start with a focused system that provides the core advantages of LDV: non-contact measurement, fast setup, and high sensitivity to vibration.
QMini's Strengths
Many users are interested in laser vibrometry, but the jump to a more advanced multi-beam system can feel too large at the beginning. QMini closes that gap without compromises.
With QMini, customers can access:
- Velocity capability: up to 48 m/s
- Frequency range: up to 62 MHz
- Measurement range: up to 300 m with suitable SpeedSync head
- Architecture: modular short- and long-range configurations
- Software: Atelier + OmmH5Viewer + UFF export
- A scalable path toward multi-beam Ommatidia systems
It is the right fit for users who want a serious vibration measurement tool without committing immediately to a 128-channel platform.
QMini & SpeedSync: Compact performance
The real strength of Qmini comes from its integration with SpeedSync.
Modular Setup
QMini and SpeedSync form a compact, modular LDV solution combining high-speed acquisition, high dynamic range, and clear single-beam readout. Different SpeedSync models support short-range and long-range configurations, and can interface with one or more Q2s or QMinis as synchronization sources.
Extended Range
The platform is designed for demanding vibration measurements that require more than basic readout. With a large frequency range of up to 62 MHz and long-range capability reaching 300 m with the appropriate SpeedSync head, it supports resonances, transients, rotating machinery, and structural response.
Software Workflow
QMini and SpeedSync also benefit from a practical software environment for data capture and processing. By leveraging Atelier and OmmH5Viewer, users can acquire, visualize, process and export in UFF and other standard formats, synchronized measurement data efficiently, making the system suitable for both entry-level testing and advanced experimental workflows.
Built for entry-level and focused test setups
Not every customer needs a multi-point measurement system for complex modal or acoustic studies.
QMini serves a different purpose.
It is built for users who want:
- one measurement point
- rapid deployment
- a straightforward signal chain
- a lower-cost entry into laser vibrometry
- a tool that is easy to understand and easy to use
- without compromising performance
This makes it highly attractive for labs, development teams, universities, maintenance teams, and engineers validating vibration behavior at one critical location.
From first measurement to future scalability
A major advantage of QMini is that it can act as a first step into the Ommatidia ecosystem.
A customer may begin with:
- single-point validation
- proof-of-concept testing
- educational use
- field vibration diagnostics
Then, as needs grow, that same customer can move toward advanced solutions for:
- multi-point vibrometry
- operational modal analysis
- structural deflection measurement
- long-range non-contact measurements
- combined 3D metrology and vibration analysis
Ideal applications for QMini
QMini is well suited to applications such as:
- Component vibration testing
Measure the response of a single critical point on a part, assembly, or prototype. - Modal testing support
Capture vibration response at selected points during experimental testing. - Machine diagnostics
Monitor vibration on motors, housings, fixtures, or rotating systems without contact. - Academic and teaching labs
Introduce laser vibrometry in a more accessible and budget-conscious format. - R&D and validation
Quickly test hypotheses and compare structural responses across design iterations. - Entry-level non-contact sensing
Replace or complement contact sensors where wiring, mass loading, or access is a limitation.
