论文摘要
该纸张涉及腰部外的单个带电的拉瓜仪横梁的边缘衍射。基于Kirchhoff-fresnel积分，分析执行光学涡流（OV）在顺序梁通过屏幕的直边封闭过程中迁移的行为。揭示了确定OV螺旋轨迹形状的衍射光束参数的通用组合。得出了描述OV位错的参数方程，得出了取决于光束筛选度的ov。此外，在弱衍射扰动条件下，在筛分到入射梁的筛分转换运动的情况下，螺旋轨迹描述了OV位置。结果，选择衍射扰动的更宽区域作为梁参数的一定变化间隔的最佳匹配函数。这项工作为解决反衍射问题的基础准备了基础：确定光束衍射相互作用的参数与光学涡流迁移轨迹的障碍物的障碍物。
The paper deals with the edge diffraction of the single charged Laguerre-Gaussian beam outside the waist. Based on the Kirchhoff-Fresnel integral, the behavior of the optical vortex (OV) migration during sequential beam blocking by the straight edge of the screen is performed analytically. Universal combination of the diffracting-beam parameters determining the shape for the OV spiral trajectories is revealed. Parametric equations describing the OV dislocation dependent on the beam screening degree are derived. In addition, the spiral trajectory, which describes the OV positions in the case of the screen-edge translatory motion across the incident beam under conditions of the weak diffraction perturbation, is obtained. As a result, the equation for a wider region of diffraction perturbation is selected as a best matching function for a certain variation interval of the beam parameters. The work has prepared the basis for solving the inverse diffraction problem: determining parameters of the beam diffractive interaction with obstacles from the migration trajectory of the optical vortex.
