无衍射贝塞尔光束经轴棱锥线聚焦后可以产生周期性局域空心光束，基于菲涅耳基尔霍夫衍射理论分别分析了椭圆加工误差和光束斜入引起的像散对轴棱锥聚焦无衍射贝塞尔光束产生的局域空心光束的影响。当椭圆加工误差或者贝塞尔光束的倾斜入射角度控制在一定的小范围内时，像散对周期性局域空心光束的特性影响不大，局域空心光束还保持它的周期性和封闭性，轴棱锥的折射率或底角越大这个范围就越小，局域空心光束就容易受到椭圆加工误差或者光束斜入射引入的像散的影响。该研究结果对周期局域空心光束的应用具有指导意义。

Periodic bottle beams can be generated by a line focusing Bessel beam illuminated on an axicon, the influence of astigmatism introduced by elliptical manufacture error and oblique illumination on the bottle beam generated by line focusing Bessel beam using axion is analyzed in terms of Fresnel-Kirchhoff diffractive theory. The influence of astigmatism on the bottle beam is not big and the bottle beam still keeps its periodicity and ring closed characteristic, as long as the astigmatism is limited in a small range. The larger the base angle or the refractive index of the axicon is, the smaller the range is, and the more susceptible to the astigmatism introduced by the elliptical manufacture error and oblique illumination the bottle beam is. The result may serve as a guideline in the application of the periodic bottle beam.
