Share your target motion and measurement requirements with our team to select a Q2 research workflow.
At Prof. Dr. Daniel Rixen’s invitation, Eduardo Margallo and Óscar Enríquez worked with Dr.-Ing. Johannes Maierhofer and the Chair of Applied Mechanics on the biomedical measurement setup.
From surface motion to spatial vibration maps
Q2 combines distance and velocity measurements without attaching sensors to the target. Researchers obtain a spatial view of vibration alongside its time and frequency response.

TUM test setup: a gelatin abdominal phantom
A gelatin abdominal phantom represented the tissue-like test surface. A simulated blood-pressure waveform drove mechanical vibrations, and Q2 measured the resulting surface-velocity field.
Phantom and optical intensity before and after surface coating
Measured results:
-
The phantom measurement setup was completed in under 15 minutes
-
Frequency peaks were measured at 4.5, 8.5, 12.5, 19.6 and 74.5 Hz
-
Velocity time series and FFT maps connected spectral response with spatial position
-
Coating the phantom surface increased the recorded optical intensity
The measurements linked frequency peaks with full-field surface response, giving the team a quantified dataset for follow-up experiments.

Arm-motion measurements at Ommatidia
Further measurements at Ommatidia captured surface motion on a human arm without attaching sensors.
The acquisition included:
-
A two-second step scan across the arm
-
A 30-second line measurement for continuous spectral data
The scans produced surface-velocity traces and spatial spectral data for investigating arm motion.
