本文用全息双频光栅剪切干涉装置对透镜几何象差的测量进行实验研究。将象差光束中两剪切干涉光线的交点看成点源,提出了用经典杨氏干涉观点、由剪切条纹图确定这些交点的空间位置而直接得到几何象差的杨氏条纹分析法。对几个透镜的象差作了测量和分析;与设计理论值作比较,二者符合良好。 In this paper, holographic double-frequency grating shear interference device for measuring the lens geometry aberration experiment. The intersection point of two shear interference light in the aberration beam is considered as the point source. The Young’s fringe analysis method is proposed to obtain the geometrical aberrations directly from the viewpoint of the classical Young’s interferometer. The shear fringe pattern is used to determine the spatial position of these intersections. The aberrations of several lenses were measured and analyzed; compared with the theoretical design values, the two were in good agreement.
