| Abstract: | The precision target positioning system applied in target chamber of high power laser facility is studied. The system utilizes digital speckle correlation method (DSC) and has theoretical precision 0.01 pixel and the position error under 8 μm. In cooperation with computer-control-step-motor, the positioning system has such advantages as automatization, high precision, large view field and non-contact etc. |
