Paper Abstract

At Turkish National Metrology Institute (UME), linear acceleration unit has been realized based on laser interferometry with different signal processing techniques. Absolute calibrations of reference accelerometers are performed by using fringe-counting and minimum point method in the frequency range from 20 to 10000 Hz. Dissemination of the linear acceleration unit to the secondary levels is carried out through a comparison calibration of vibration pick-ups by "backto- back" method. Traceability chain for calibrations of the vibration calibrations and measurements performed at UME has been described in this paper.
