New Techniques in Primary Accelerometer Calibration
Mark I. Schiefer
Abstract:
This paper will discuss a newly developed implementation of ISO 16063 style primary accelerometer calibrations. The goal is a laser primary accelerometer calibration system capable of performing low uncertainty primary accelerometer calibrations while maintaining the throughput and simplicity of a traditional back-to-back calibration system. Primary accelerometer calibrations typically require multiple measurement passes at several locations across the device to be calibrated by primary means. This paper discloses the novel use of a dual beam, simultaneous primary calibration laser interferometer based system. The use of dual beam and multiple pass Michelson Interferometers greatly improves not only the reliability of the measurement, but significantly simplifies the setup and measurement process of primary laser calibrations of accelerometers.
