论文摘要
从理论上讲，我们研究了圆尖axicon的不同形状的液滴准贝丝束。证明了描述axicon后面电场振幅的轴向分布的菲涅耳衍射积分的精确溶液。对精确溶液的分析表明，“轻液滴”的周期不是恒定值，而是取决于轴向距离和隔离膜表面远离圆锥形远离圆形区域的偏差。预测的效果可以用于重建无3D扫描而无需3D扫描的阳极表面的确切形状。
We theoretically investigate droplet quasi-Bessel beams for different shapes of the round-tip axicon. Exact solutions for the Fresnel diffraction integrals describing the axial distribution of the electric field amplitude behind the axicon are demonstrated. The analysis of the exact solutions shows that the period of «light droplets» is not a constant value, but depends on the axial distance and on the deviation of the axicon surface from the conical shape far from the rounded region. The predicted effect can be applied for the reconstruction of the exact shape of the axicon surface without 3D scanning.
