Vibration analysis by laser scanning vibrometry
Acoustics
| Measurements | Vibration velocity and displacement, vibration and modal analysis |
| Measurement object | Machinery, equipment, installations, tools, components, panels, shells, etc. |
Technical data
| Laser | Helium-neon laser (λ = 633 nm) |
| Frequency range | 0 to 40 kHz |
| Measuring range | 0.5 μm/s to 2.5 m/s (vibration velocity) |
Special features
- Contact-free measurement of vibrating objects and surfaces
- Automatic scanning of a free definable point grid on the surface
- Visualization (graph or film) of vibration modes of the measuring objects
More information
- Locating of zones with maximum vibration in case of real or ideal excitation
- Optimization of the vibration characteristics of components
- Combination with acoustic near-field holography for determination of radiation factor
- Data export to other software for refined analysis
