The deformation process of material shocked by strong and short pulsed laser has high strain rate. Response bandwidths of many testing instruments are not wide enough to effectively measure the deformation process. The velocity interferometer system for any reflector (VISAR) commonly used to test dynamic deformation is complex and expensive. Especially it has the drawback of lacking stripes. A simple and novel optoelectronic measurement system is applied to measure the deformation. With the calibration of ratio of the output voltage and the deformation, the displacement and velocity of shock center can be worked out. The displacement and velocity law are similar with the simulation result reported. The average deformation velocity in shock period is calculated as 8.49×104 m/s. The analysis of the data, based on the fitting curve, shows that the deformation is superimposed the movement of damped oscillations and elastic deformation. Meanwhile, the vibration velocity and the plastic deformation of plate can be obtained through the fitting coefficient. These results provid a basis platform for the analysis and control laser shock deformation process.
