VibroMap — Full Field Laser Vibrometer

Overview

VibroMap is a full‑field laser vibrometer designed for real‑time, non‑contact vibration measurement of mechanical structures, composites, and micro‑components. Using interferometric imaging, VibroMap captures complete mode shapes across the entire surface in a single acquisition — eliminating the need for point‑by‑point scanning.

Engineers and researchers use VibroMap to analyze resonance behavior, detect structural defects, validate simulations, and characterize dynamic performance with high spatial and temporal resolution.

Key Features

  • Full‑field vibration measurement — all points measured simultaneously
  • Real‑time mode shape visualization
  • High‑frequency capability (DC to high‑MHz range)
  • Non‑contact, non‑destructive
  • High spatial resolution (camera‑limited)
  • Robust to environmental motion
  • Fast measurement cycles for R&D and production environments

Measurement Principle

VibroMap uses interferometric imaging to measure out‑of‑plane vibration:
  1. A coherent laser illuminates the surface.
  2. Reflected light interferes with a reference beam.
  3. A high‑resolution camera records the interference pattern.
  4. Phase extraction algorithms compute displacement for each pixel.
  5. Mode shapes and frequency responses are reconstructed in real time.

Because every pixel acts as an independent detector, VibroMap captures complete vibration fields instantly, even at high frequencies.

Measurement Workflow

  1. Mount the object
  2. Illuminate with the integrated laser
  3. Adjust focus and reference beam
  4. Apply excitation (optional)
  5. Acquire interferometric images
  6. Extract phase and compute vibration data
  7. Visualize mode shapes
  8. Export results for analysis or reporting

The workflow is deterministic, repeatable, and optimized for rapid iteration.
