| 摘 要： | 基于像传递的激光自动准直技术是提高准直准确度、增加稳定性的好方法。本文在理论上用两快速傅里叶变换（ＦＦＴ）分析了准直中基于像传递的近远场信号对图像处理影响。在光束近无场像面上引入十字叉丝并以“神光”装置的某一级空间滤波器为例，计算出光束直径一定时合适的十字叉丝尺寸；最后通过实验确定了基于像传递的自动直技术的具体实现系统。

| Abstract: | The image transfer based automatic laser alignment technique is a good way for improving the alignment accuracy and increasing alignment stability. The effects of this technique on the image processing is analyzed theoretically by two dimension FFT simulation. The matched cross-hair width for one spatial filter in “Shenguang Facility” is calculated. A detailed image transfer based alignment system is given. |
