Q2S Laser RADAR
Q2S Laser RADAR for multi-point structural monitoring
Measure vibration simultaneously at 65 fixed points across a structure—with no mechanical scanning.
Q2S combines remote, non-contact vibration measurement with 3D geometry to support repeatable monitoring of bridges, infrastructure and other large structures.
Measure vibration simultaneously at fixed points across the structure
Q2S uses 65 parallel channels to acquire repeatable measurements across a defined field of view. Because the points are captured simultaneously, the instrument does not rely on mechanical scanning to build the response.
Fixed measurement points
A stable optical geometry keeps the same points in view for repeatable measurements and monitoring.
Simultaneous multi-point capture
All 65 channels measure in parallel at up to 40 kHz per channel in the standard configuration.
Non-contact and remote
Observe structural response without attaching sensors to the measurement points.
From vibration response to structural health
Q2S connects dynamic response with geometry so teams can measure movement, reconstruct structural behaviour and monitor changes over time.
1. Measure
Capture vibration at 65 points simultaneously, including velocity and derived displacement.
2. Reconstruct
Use geometry-linked data to interpret spatial structural behaviour and strain.
3. Monitor
Repeat the same fixed-point measurement geometry for continuous or long-term observation.
Built for bridges and long-term structural monitoring
Q2S is designed for fixed installations where structural response must be captured repeatedly without contact. Its simultaneous channels and integrated environmental compensation support bridge, infrastructure and continuous monitoring workflows.
- Atmospheric compensation using pressure, temperature and humidity
- IP54 enclosure and 0–40 °C operating range
- Up to 240 minutes of battery operation
From velocity to displacement and strain
Q2S measures vibration velocity with a sensitivity below 50 nm/s/√Hz. Geometry-linked processing supports displacement sensitivity below 0.1 nm and strain sensitivity below 1 µstrain.
For high-speed or extended-range measurements, the modular SpeedSync configuration reaches sampling rates up to 125 MHz, velocities up to ±47.9 m/s and distances from 0.3 to 300 m.

Domande sul monitoraggio strutturale con Q2S
Q2S unisce la misura simultanea delle vibrazioni su 65 punti alla geometria fissa per un monitoraggio strutturale ripetibile.
Cosa misura Q2S?
Q2S misura simultaneamente la vibrazione su 65 punti fissi e collega la risposta alla geometria 3D. Velocità, spostamento derivato, comportamento spaziale e dati di deformazione supportano l’analisi di ponti, infrastrutture e altre grandi strutture.
Con quale velocità e sensibilità misura Q2S?
La configurazione standard acquisisce tutti i 65 canali in parallelo fino a 40 kHz per canale. La sensibilità di velocità è inferiore a 50 nm/s/√Hz; l’elaborazione legata alla geometria raggiunge meno di 0,1 nm di spostamento e meno di 1 µstrain di deformazione.
Come supporta Q2S il monitoraggio esterno ripetibile?
La geometria ottica fissa torna sugli stessi punti per osservazioni ripetute o continue. Custodia IP54, campo operativo 0–40 °C e compensazione ambientale integrata supportano installazioni permanenti su ponti e infrastrutture.
Quali distanze e velocità copre Q2S?
Il funzionamento standard copre 0,5–50 m. Le configurazioni modulari SpeedSync estendono la portata a 0,3–300 m, il campionamento a 125 MHz e la velocità misurabile a ±47,9 m/s.
