Abstract: By vacuum laser zone-plate diffraction imaging based on three points method, a full automatic vacuum deformation monitoring system is developed and applied to deformation monitoring of a straight concrete dam successfully. The system has four main characteristics; first, fully automatic, under the control of main computer the whole system can measure horizontal and vertical deformation simultaneously according to settled schedule; second, high accuracy, depending on specially designed receiver and algorithm, precision 0.1 mm, resolution 0.01 mm are achieved; third, fully sealed, the whole system is fully sealed which will protect the measuring system from ambient disturbances; last, the ability to operate internet communication and control, through internet host computer can not only communicate with the measuring system but also control the whole system entirely.
