Digital vibrometer systems utilize the latest technologies for digital signal acquisition and processing. They are based on a purely numerical Doppler signal decoding technique, where displacement and velocity information is not recovered by analog demodulators but by powerful data processing algorithms.
Various Polytec solutions are suitable for difficult and stringent applications as measurements in data storage, micro-electro-mechanical structures (MEMS) or hearing dynamic applications.
Very high and stable accuracy, linearity and flatness of frequency response
For calibration purposes only digital LDVs are applicable
Displacement resolution down to an impressive 0.002 nm (VDD)
Velocity resolution down to 0.02 µm/s/ÖHz (PDV-100, IVS-300)
