Design and application of the Precision Checking Device for Novel Vacuum Laser Collimation System
In order to ensure the validity of dam safety monitoring data,improve the level of dam safety monitoring,and assure the safe operation of hydropower stations,the precision checking device of vacuum laser collimation system was designed and developed in this paper,which given the linear displacement of the zone plate through the outside of the measuring box,and checked measurement accuracy of the system.The measurement principle and structure of the precision device were introduced in detail,and it was applied to a dam project of a water conservancy project for field testing.The test results show that the precision device can provide a strong inspection technical support to ensure the accuracy and reliability of the system measurement data.
