Laser vibrometry
 |
Laser vibrometry is contactless measurement of the displacement and/or speed of an object a point on an object according to a sensitivity vector.
- Frequency range : 0 to 1.5 MHz depending on the size
- Maximum measurable deployment : ± 41 nm
- Maximum measurable speed : ± 10 mm/s
- Resolution : 2 nm for displacement and 0.5 µm/s for speed
- Operating distance up to 30 m
