Abstract
In this work is presented a relative based interferometry technique with homodyne and heterodyne detection for accelerometers absolute calibration in the range between 10 Hz and 10 kHz with accelerations of 0.5 to 400 ms-2. The experimental systems implemented and the acquisition and the developed data processing modules are described. The results obtained as the uncertainty budget for all the measuring range is evaluated, describing the mathematical models and identifying the corresponding uncertainty sources.
