Two options are available:

• NDV-Vibro-LF for analysis of oscillations at frequencies of up to 2 kHz (built-in CW laser 50 mW)
• NDV-Vibro-HF for analysis of oscillations at frequencies of up to 30 kHz (external CW laser up to 18 W; high-speed computer vision camera)

Specification:

Displacement sensitivity: no less than 0.01 µm

Realized measurement methods:

• Stroboholographic Method – measurement of vibration displacement fields under periodic oscillation of the object suitable for recording a video;
• Multi Exposure Method (registration of a series of frames with a frequency of up to 30 kHz) – measurement of displacement fields under non-periodic vibrations with recording a video;
• Real-Time Observation Mode of the vibration process.

Examples of application:

1. Visualization of free vibration modes and measurement of vibration displacement fields of the test object.
2. Rapid visualization of displacement fields with the method of electronic speckle interferometry.
3. Visualization of vibration displacement field under resonant oscillation of the test object as a time function (an interferometric video).
4. Measurement of vibration displacement fields of the nanometer range.
5. Visualization and measurement of vibration displacement fields under multicomponent oscillations.
