Abstract

Accurate phase response information for vibration measurements is becoming more important for a vast range of applications. The use of laser interferometry to perform phase calibration of accelerometers is examined, specifically through the implementation of the sine-approximation method as described in ISO 16063-11. Phase calibration of the components of a measurement setup is discussed, considering the effects and influence that each component has on the phase calibration of accelerometers. The accuracy obtainable for phase calibration of accelerometers is evaluated by means of comparison measurements between two National Metrology Institutes. In conclusion, the uncertainty contributors as presented inthe ISO 16063-11 with respect to phase calibration are reported on.
