The core of the SmartTable is an advanced damping technology called Intelligent Q (IQ) Damping. It effectively addresses the medium frequency resonances of optical tables by incorporating two pairs of sensor and actuator in the optical table design and use an external controller to coordinate the signal processing, enabling the fast and accurate damping response for optical tables. Each sensor-actuator pair is controlled by a separate control channel. The sensor senses the vibrations and the actuator outputs 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.
Active damping upgrade kits are used to upgrade SmartTable® UT2 table top and OTS-UT2 table system to hybrid damping performance. IQ dampers are normally used with typical laboratory size optical tables (up to 12 ft. or 3.5 m long) and other relatively small vibration-isolated structures with the lowest natural frequency of flexural vibration above 100 Hz. IQD dampers are optimized for use with larger structures, in particular with the custom doubled optical tables having the lowest natural frequency of flexural vibration in the 40 - 100 Hz range.
The SmartTable controller serves as the signal processing hub and feedback the processed signal to the active dampers integrated with the optical table. The all-new ST-300 controller features more reliable and powerful data processing capabilities and better damping assistance, providing the strongest support for the IQ damping technology.
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.
The Nanostructures shown in the images above were built on and imaged with a Newport SmartTable optical table top. The image on the left was built with SmartTable active damping disabled. The image on the right was built with SmartTable active damping enabled. Source for images: Steven E. Kooi, Ph.D. Research Engineer, Institute for Solder Nanotechnologies, MIT
