摘要

由菲涅耳衍射理论出发详细地分析轴棱锥顶点加工误差对光束传输特性的影响。分析指出，当轴棱锥顶点加工成圆形时，它相当于一个平凸镜，对光束起点聚焦作用；而双曲线顶点模型更贴近真实加工的轴棱锥，这时衍射光束因为干涉原因产生振荡，形成畸变无衍射光束。文章理论推导了不同顶点加工轴棱锥的衍射光场表达式，模拟分析了光束传输变换特性，最后针对双曲线顶点加工的轴棱锥提出改进方案，修正后的光束特性效果理想，对实际加工的轴棱锥应用具有很好的指导意义。

Abstract

Based on the Fresnel diffraction theory

the influence of the axicon with vertex manufacture precision is analyzed in detail. It is equal to a plano-convex lens focusing the beams when the vertex is machined to a circle. The blunt-tip region of a real axicon can be described actually by a hyperbola

and the aberration non-diffracting beams will be formed for the interference oscillation. We present the theoretical derivation

simulation analysis of the beam propagation and transformation with different vertex manufacture of the axicon. Finally

a method of modifying the influence of a hyperbola-tip axicon is proposed and the correction effect is ideal that is guiding significance to the application of the real manufacture axicon.
