【Abstract】 The principle and characteristics of quadrature Michelson laser interferometers are fully described. The sine-approximation method of the sensitivity magnitude and phase calibration of accelerometers is introduced in detail, as well as phase unwrapping algorithm, quadrature corrections and the least squares fit algorithm are discussed. Based on this, an automated accelerometer calibration system is developed with the help of virtual instrument technology, which is of great importance in the field of vibration calibration.更多还原
