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 meet contactloos de trillingssnelheid van een zichtbaar oppervlak langs de zichtlijn. Het meet niet rechtstreeks de luchtdruk van geluid zoals een microfoon. Wanneer geluid een paneel, membraan of behuizing exciteert, toont de oppervlaktebeweging de structurele respons. Leg vast of u oppervlaktetrilling, een modevorm, akoestische proxy of microfoongekalibreerde grootheid nodig hebt. Een oppervlak straalt geluid uit of reageert erop volgens modi, randvoorwaarden, materiaal en excitatie. Gelijktijdige meting van veel plaatsen toont ruimtelijke patronen, resonanties en transiënten. Voeg een microfoon-, kracht-, toerental- of tijdreferentie toe wanneer correlatie met geluidsdruk, bedrijfsorde of bekende excitatie nodig is. Q2 biedt 65 gelijktijdige optische kanalen en tot 1.300 punten met 20× ruimtelijke oversampling. Q-Series-systemen meten trillingssnelheid tot ±155 mm/s en plaatsen data op gemeten geometrie. Optische toegang, retour, afstand, bewegingsband en referentiekwaliteit bepalen het resultaat. Gebruik een microfoon als de vereiste grootheid luchtgeluidsdruk, niveau of een gekalibreerd akoestisch veld is. Een hybride test verbindt dat resultaat met de beweging van een constructie op afstand. Definieer tijdsynchronisatie, coördinaten, omgeving, kalibratie, onzekerheid en de beslissing die elk kanaal ondersteunt.
