Q2 Laser Doppler Vibrometer succeeds in measuring vibration on dark, porous automotive materials and surfaces that typically defeat conventional optical systems. Showing stable, full-field, contactless measurements without surface preparation, enabling more accurate NVH and interior acoustic validation.
Q-Series brings interferometric precision to bridge monitoring and structural health management. Using massively parallel FMCW LiDAR and photonic integration, it measures deflection and vibration across entire bridge spans, without contact or traffic disruption. From live-load deflection tests to digital twin development, allowing scalable, real-time insight into infrastructure performance and safety.
Speckle noise has long limited the accuracy of coherent laser vibrometry, especially on rough or composite surfaces. Ommatidia’s SpeckleGuard™ technology tackles this challenge using compound aperture diversity and real-time fusion to stabilize velocity measurements across multiple beams. The result is cleaner data, higher measurement coherence, and reliable vibration analysis without surface preparation—even in demanding industrial or research environments.
Printed circuit boards used in space, defence, aeronautics, and transportation must endure extreme vibration without failure. Traditional accelerometer-based testing can’t reveal how individual components behave under load. Ommatidia’s massively parallel Laser Doppler Vibrometry (LDV) and Laser RADAR technology enable non-contact, high-resolution vibration analysis across entire PCBs—identifying failure-prone areas, validating designs, and ensuring reliability in critical applications.
In a groundbreaking collaboration with WEG, Ommatidia deployed its Q2 Laser RADAR across four operational testbeds—from buzzing transformers to high-frequency electric motors—demonstrating the power of real-time, contactless vibrometry in harsh industrial environments. These case studies reveal how spatially-resolved vibration mapping and full-spectrum analysis are transforming predictive maintenance, NVH diagnostics, and quality control in electric machinery.
