Intelligent Q (IQ) Active Damping Technology

At the core of our SmartTable optical table tops is an advanced damping technology called Intelligent Q (IQ) Damping. It effectively addresses the medium frequency resonances of optical tables from 80 to 550 Hz by incorporating two pairs of sensors and actuators in the optical table top design. An external controller is used to coordinate the signal processing, enabling a fast and accurate damping response. Each sensor-actuator pair is controlled by a separate control channel. The sensor senses the vibrations and the actuator outputs a signal to compensate for the vibrations. The pre-amplifiers and band-pass filters condition the sensor output signal before feeding it to the digital controller. The digital controller implements recursive filters that compensate for the dynamic response of the shaker and correct the phase to bring the phase difference between the displacement and force close to (-π/2) in the desired frequency range.

Easy Set-up with One-Button Auto Tuning

SmartTable active damping products are easy to set up and operate. Simply connect the IQ dampers with controller and press "Auto-Tune" button on the controller, the system will automatically find the resonances of the table and set gain parameters. Once the tuning is finished, the dampers will start working to damp vibrations on your tabletop real time. This feature also enables users to improve their table performance under different payload or payload distributions - press "Auto-Tune" when you have a major change in your set up to achieve the maximized damping performance.

24/7 Vibration Monitoring Capability

The ST-300 active damping controller comes with powerful and intuitive software that allows user to generate FFT plots, time response plots and save graphs or export data for further analysis. The ST-300 software also provides time continuous 10 to 820 Hz vibration data monitoring that could be used as a system trouble shooting tool for long duration experiments.

Effective Active Damping

When the IQ damping system is activated, the motion on the table is minimized. Active damping eliminates main resonance vibration peaks in vibration spectra created by random excitation, particularly in the sensitive 100-300 Hz range.

Faster Settling Time

Compared with broadband damping technologies, IQ damping provides much more accurate and timely compensation across the entire working ranges of the actuator-sensor pairs, delivering a quiet tabletop surface for any challenging applications.
