中文摘要：
分析圆顶轴棱锥与理想轴棱锥对Bessel光束的聚焦特性.基于广义的惠更斯-菲涅耳衍射积分理论推导出Bessel光经过理想轴棱锥和圆顶轴棱锥后的光强表达式,并对理想轴棱锥与圆顶轴棱锥聚焦的Bessel光束的传输特性进行描述,数值模拟不同截面下的光强分布图和径向光强分布图.研究结果表明：圆顶轴棱锥和理想轴棱锥都可以产生周期性的局域空心光束（Bottle beam）,但是相比于理想轴棱锥,圆顶轴棱锥所产生的Bottle beam周期较短,并且中心光强较强,暗斑尺寸较小.
英文摘要：
This paper analyzes the focal characteristics of the vaulted axicon and ideal axicon on Bessel beams.The expressions of light intensity of Bessel beam passing through an ideal axicon and a vaulted axicon are derived based on the generalized Huygens-Fresnel diffraction integral theory.This paper also describes the transformation of Bessel beam focused by the ideal axicon and vaulted axicon,and numerically simulate the light intensity distribution graph and intensity distribution of radial in different cross sections.Studies show that vaulted axicon and ideal axicon could both produce periodical Bottle beams.However,compared to ideal axicon,the Bottle beams produced by a vaulted axicon have shorter cycle time,stronger central light intensity and smaller size of dark spots.
