Paper Abstract

Measurement results about instant displacement and its associated velocity on an interferometric setup for shock calibration of accelerometers are studied; fitting methods for displacement and velocity from which peak-acceleration shock is computed, are compared using a least squares error criteria. Computation of instant parameters from interferometric signals are based on zero-crossings evaluation and their corresponding time-intervals. Voltage outputs from an accelerometer-amplifier chain are also analyzed.
