Abstract: When vibration table vibrates in high frequency, dynamic angle error is induced. This dynamic angle is not anticipated, it is considered a kind of error of the vibration. A dual-frequency laser interferometer is used to measure the dynamic yaw angle、 pitch angle and roll angle respectively when vibration table vibrates in 2 000Hz. In this dynamic angle measurement method laser interference theory is used. We find the vibration of surroundings influences the result greatly by analyzing the test result. A study direction is found to prefect the dynamic angle measurement method.
