Automation system of laser collimation for monitoring deformation of dam

摘要

The Automatic system of laser collimation for monioring deformation o f dam which has high accuracy is researched and manufactured in CHina. It's very good for monitoring horizontal shift and vertical shift at the dame time. Because of the differences of laser propagating medium, there are two kinds of system including vacuum laser collimation and air laser collimation. The cardinal of horizontal shift can be gotten from vertical shift. The cardinal of vertical shift can be gotten from the device of double metal height mark. So it realizes computer automatic monitoring absolutely. During the application of several dams in China, it proves that the system is very sucessful.
