For NVH engineers, acoustics researchers, industrial monitoring teams, and building security specialists, the challenge of measuring vibration and sound has always been one of trade-offs.
Working on a remote acoustic or NVH measurement?
Tell us the target, frequency range, stand-off distance and whether you need point, full-field or 3D vibration data. We will help identify the practical workflow.
Traditional tools, such as accelerometers, microphones, and strain gauges, can provide valuable point data, but they are:
- Intrusive
- Time-consuming to install
- And often alter the dynamics they are meant to observe
In high-stakes environments such as aerospace structural testing or transformer monitoring, those limitations introduce risk, cost, and uncertainty.
This is where non-contact sensing, and specifically Laser RADAR combined with optical vibrometry, is helping to redefine the field we work in.
This article explores how laser-based remote sound sensing works, why it matters, and how organisations are using Ommatidia’s Q2 Laser RADAR platform.
Why Non-Contact Vibrometry Matters
Traditional accelerometer or microphone-based methods face three critical issues: Using interferometry and FMCW LiDAR principles, the Q2 measures displacement, vibration, and acoustic signatures remotely. This approach improves accuracy and enables large-scale surveys that are impractical with conventional sensors. Vibration maps for detected peak frequencies The Q2 Laser RADAR is designed for applications that demand precision and scalability. It integrates high-accuracy 3D metrology with advanced vibration sensing to replace multiple instruments with a versatile platform. Key specifications include: The Q2 also integrates seamlessly with Industry 4.0 architectures, offering autofocus, angular scanning, and an RGB camera for intuitive programming and visualization. Learn More About the Q2 Laser RADAR → The Q2 Laser RADAR addresses a wide range of technical use cases: Full-field vibration maps reveal resonance, damping, and aeroelastic effects in automotive and aerospace structures without mass loading. In rotating machinery, transformers, or production lines, the Q2 delivers remote monitoring (without downtime) and supports early fault detection. Researchers studying façade vibration, traffic-induced noise, or barrier performance access full-field acoustic behavior without microphone arrays. Remote sound sensing provides standoff monitoring capabilities for high-security facilities, enabling vibration and acoustic analysis. Q2 Laser Radar enables NDT capturing of high-resolution vibrometry data These examples highlight how the Q2 Laser RADAR provides non-intrusive, scalable, and high-resolution insights.

This makes Laser RADAR a core tool for NVH, acoustics, and structural monitoring. For teams responsible for vibration testing, modal analysis, structural health monitoring, or building acoustics, the Q2 Laser RADAR represents a change in capability. By unifying optical vibrometry with high-speed laser radar scanning, it delivers the precision and efficiency needed for today’s most demanding projects.

Laser RADAR acquisisce a distanza la velocità di vibrazione lungo la linea di vista di pannelli, membrane, involucri e strutture visibili. Quando il campo acustico eccita il bersaglio, il moto superficiale misurato mostra dove e come risponde la struttura e fornisce forme vibranti spaziali e velocità per l’ingegneria acustica. Una superficie vibra e irradia o risponde al suono secondo modi, vincoli, materiale ed eccitazione. Misurare molti punti simultaneamente mostra pattern spaziali, zone risonanti e transitori. Integrare microfono, forza, regime o riferimento temporale quando serve correlare pressione sonora, ordini operativi o eccitazione nota. Q2 offre 65 canali ottici simultanei e fino a 1.300 punti con sovracampionamento spaziale 20×. I sistemi Q-Series misurano velocità di vibrazione fino a ±155 mm/s e collocano i dati sulla geometria misurata. Accesso ottico, ritorno, distanza, banda del moto e qualità del riferimento determinano il risultato. Laser RADAR fornisce dati densi del moto superficiale senza contatto, mentre i microfoni forniscono riferimenti sincronizzati di pressione e livello sonoro aereo. Insieme collegano il campo sonoro al moto della struttura remota; tempi, coordinate e calibrazione condivisi supportano identificazione delle sorgenti, analisi dei percorsi di trasferimento e progettazione acustica.
