Vibration Analysis

The Digital 3D Image Correlation System Q-450 allows the dynamic measurement of full-field three dimensional displacements and the subsequent analysis of strains on almost any type of material and components.

Based on the digital image correlation technique, the Q-450 system, as the high speed configuration of the Q-400, is designed for full-field vibration analysis and high speed deformation measurements.

E.g. airbag testing and development, fracture mechanics  and shock excitations, as well as for dynamic strain measurements, e.g. in fatigue tests.
An easy calibration procedure supports the quick setup of the system.

Dynamic Measurement Range
The system uniquely combines the high spatial resolution of full-field optical measurement with high temporal resolution. The dynamic range is from static to more than 20.000 Hz, with the capability to measure displacements from the μm-range up to several 10 cm. The resolution corresponds to 10-5 of the field of view, e.g. a few μm for A4 paper size measurement area.

Strains ranging from 100 μStrains up to several 100 percent can easily be measured.
