贝塞尔光束通过光阑-透镜分离系统的焦移
Focal shift in Bassel beams focused by an aperture-lens separation system
-
摘要: 利用Collins衍射积分公式推导了贝塞尔光束通过光阑透镜分离系统后的轴上光强分布公式,并详细分析了这一情况下的焦移。依赖于光阑透镜的分离程度其相对焦移可能相反。Abstract: In the paper,the expression for axial intensity distribution of Bassel beams passing through an aperture lens separation system is derived based on Collins formula.The focal shift may be reversed,depending on the aperture lens separation.
