Areas of application
- Measurements: Non-contact analysis of deformations, stresses and vibrations.
- Rotor blade deformations: Measurement on wind turbines in operation.
- Component analysis: Stress and modal analyses on machine components.
Functionality and advantages
- Measurement principle:
- Comparison of reference and measurement images to calculate displacements and stresses.
- High-precision sub-pixel interpolation enables movement resolutions of up to 0.01 pixels.
- Large-scale vibration analysis using high-speed cameras.
- Advantages:
- Flexible application in 2D or 3D with one or more cameras.
- Measurements possible from acute angles and in different surface textures.
- Non-reflective surfaces or applied textures optimize measurement accuracy.
Measurement variables
- Basic requirements:
- High-contrast, non-reflective surfaces.
- Optional textures: printed films, sprayed patterns or toner-coated surfaces.
- Measurement variables:
- Deformation and elongation.
- Stresses and damping.
- Frequencies (FFT) for vibration analysis.
- System configuration:
- One camera: Limited motion analysis in the plane.
- Two or more cameras: Precise three-dimensional tracking of movements.
