光学CT方法用于大坝垂线坐标的检测

把光学ＣＴ技术应用于大坝变形垂线坐标的测量，研制了用阵列光源和电荷耦合器件ＣＣＤ线阵构成的一种新型垂线坐标仪。工程现场测试资料表明，该坐标仅用观测精度高，稳定可靠并能自动化监测的优点。

Optical CT applied to dam pendulum wire coordinate measurement

The optical CT technique was applied to pendulum wire coordinate measurement for dam deformation monitoring.A new type of pendulum wire coordinate gauge was developed which consisted of point light source array and CCD linear array.Field test data shown the advantages of high accuracy,stability and reliability as well as enable of automatic monitoring of the coordinate gauge.
