摘要
由衍射理论和干涉理论及其几何光学系统地研究几种不同轴棱锥的光传输特性。分别对传统轴棱锥、开诺全息型轴棱锥、椭圆轴棱锥和梯度轴棱锥的特性进行相关的模拟分析。结果表明,开诺全息型轴棱锥可以得到传输距离更长的无衍射光束,椭圆轴棱锥可以把斜入射光束转换成无衍射光束,而梯度轴棱锥可以把入射光束直接转换成应用更为广泛的空心光束。
Optical transport characteristics with different axicon models were studied systematically based on the diffractive and interferential theory and geometry optics. The characteristics of traditional axicon, kinoform-axicon, elliptical axicon and gradient-axicon were simulated and analyzed respectively. Based on the simulation analysis results, propagation-invariant beams with long non-diffracting distance was generated by kinoform-axicon; beams oblique incidence were also converted to non-diffracting beams by elliptical axicon; and bottle beams with much more extensive application can be obtained directly by gradient-axicon.
