摘要
研究了用于SG-II装置光束精密瞄准的激光束自动控制系统。用傅里叶光学分析可知,探测激光束位置取 于空间滤波器像传递面,这时近远场像面上衍射噪声最小,光束自动调整时,近远场关联又最小, 可以各自独立调 整。计算机CCD图像处理闭环系统实现了光束自动控制。误差分析和SG-II全系统光束自动控制实验表明, 光束 瞄准精度<1"。
Abstract
The laser beam automatic control system is applied in the beam collimation of the laser fusion facility of "SG-II. It can be inferred from the optical analysis of Fourier, the image noise of the near and far-field caused by diffraction is the least when the near and far-field which are to detect the location of the laser beams are on the image-relay plane of the spatial filter. When correcting the beams automatically, the correlation of the near and far-field is also the least so that they can be adjusted independently. The image processing makes the automatic alignment realized with the computer and CCD camera. It can be shown from the error analysis and the experiment of automatic alignment of the system that the precision of the beam position is less than 1".
