用相关测量技术实现精确靶定位技术研究
Precision Target Positioning by Digital Speckle Correlation Measurement
摘要
介绍了一种高功率激光装置中用于X光实验的精确靶定位系统．该系统采用数字散斑相关测量的方法,其理论精度为0.01个像素。整套系统在实际运用中的误差小于8 μm。该系统与计算机控制的步进电机配合使用,具有自动化程度高、大视场高精度和非接触性等优点。
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.
