Paper Abstract

A heterodyne laser interferometer and a PXI bus instrument make a primary acceleration calibration system. The modified heterodyne laser interferometer has a frequency stabilized laser and a high frequency accuracy Bragg cell. The system is capable of vibration (both sinusoidal and random) and shock calibration. This paper introduces the principle of the system. An accelerometer is calibrated by this system using different exciting signals include sinusoidal, random and half-sin. It shows the system is flexible in primary vibration and shock calibration and high accuracy will be attainable.
