Abstract

According to the image relay concept in the optical amplification system, submicrometer resolution of a digital image processing system has been given in this paper. The accuracy and precision of the system has been examined by using a standard identification reticle, and some measurement results of a small focal spot through a computer generated holographic lens have been given.
测量小光束直径的新方法
根据光学放大系统中的图像中继概念,给出了数字图像处理系统的亚微米分辨率。用标准的识别标线对系统的精度和精度进行了检验,并给出了用计算机生成的全息透镜对小焦斑的测量结果。
