| Abstract: |
| Since accelerometers are widely used in seismic exploration, rail transportation and other significant fields, transverse sensitivity become an important item in calibration and application of accelerometers. Testing methods for accelerometer transverse sensitivity are described according to the acceleration vector dimensions. Limitations of testing methods and corresponding testing setups relating to transverse sensitivity amplitudes, frequencies and angles are discussed as well as the current research progress . In the final section, key points of future investigations are presented |
