Signal Processing

Digital decoders convert the recorded intensities in real time into the displacement, velocity, and acceleration data

Digital Signal Processing

OptoMET relies on an end-to-end digital signal processing. This avoids the drawbacks of analog demodulation which may result from component aging, temperature dependencies, noise and non-linearities.  Significantly higher sensitivity, better resolution and stability are the benefits of OptoMET’s end to end digital signal processing. Extremely low noise levels produce precise results even from poorly reflecting measurement objects.

The OptoMET ultraDSP-Technology

The OptoMET ultraDSP-Technology combines efficient algorithms with specialised, high performance processors. Decoders are integrated into the vibrometer, no separate hardware is required. Due to their energy-efficient design OptoMET vibrometers can be passively cooled and be operated independent from grid power. Signal processing is done in real time. Special FIR filters allow for reliable and precise measurement even under the most challenging conditions.

Measurement Data

Each second 160 million values for displacement, velocity, and acceleration can be recorded and passed to the user. Data are transferred through a standard GBit-Ethernet port and simultaneously via three BNC connectors for the integration in analog test environments.
