long focal lens

In the driver of the Inertial Confinement Fusion (ICF), the spatial frequency filter is the important module of system, with functions of filtering out high-frequency noise, enlarged beam and image relay, but high-accuracy measurement of focal length and wavefront of long focal lens which composed one is difficult on test of optical components in ICF.

本论文旨在对长焦距透镜面形检测方法进行新的探索,提出了基于Ronchi光栅泰伯效应的扫描测量法,可以大大提高检测效率,并给出定量的检测结果。
