= Active Vibration Isolation

Particularly it is critical for the optimum operation of the Molecular Measuring Machine M3 a high resolution length metrology instrument at the National Institute of Standards and Technology NIST NIST is investigating active vibration isolation as an approach


PDF SACE scanning process assisted with ultrasonic vibration

·Furthermore machining experiments of the micro SACE scanning process by constraining discharges to tool electrode end were verified on ZrO2 ceramics as a kind of difficult to machine material


PDF Vibration Analysis for Machine Monitoring and Diagnosis…

·The vibration signatures of the machines contain important information regarding the machine condition such as the source of failure and its severity Operators are also provided with an early


Magnet assisted stage for vibration and heat reduction in wafer scanning

·Assistive forces are applied to the scanning table during motion reversal MR regions using a pair of repelling permanent magnets PMs at each end of the stage The assistive forces provided by the PMs are channeled to the ground rather than to the vibration sensitive machine base thus reducing residual vibration and enhancing scanning speed


Vibration resistant interference microscope with assistant focusing

·Vibration resistant interference microscope with assistant focusing for on machine measurement of surface topography PSI To realize a favorite π/2 phase shifting a mechanical scanning with an increment of one eighth of wavelength is required If the wavelength of the illumination light is 600 nm the scanning increment is only 75 nm


Magnet assisted stage for vibration and heat reduction in wafer scanning

·A schematic of the x axis of a wafer scanning stage with PADs denoted by dotted springs is shown in Fig 1 b The scanning table actuated by motor force F M is mounted on a rigid base is isolated from ground vibration using very soft springs typically pneumatic isolators in order to achieve the desired precision in the CV regions [6]


Mirau type coherence scanning interferometer with integrated vibration

·We present a Mirau type coherence scanning interferometer CSI with an oscillating reference mirror and an integrated interferometric distance sensor IDS sharing the optical path with the CSI


A Portable Scanning Device for Local Vibration Testing

·Abstract In this study the effectiveness of local vibration testing using a portable scanner and machine learning for non destructive inspection of concrete struc tures was examined Using a portable vibrator and laser vibrometer local through thickness vibration tests were conducted on specimens of concrete beams and a
