摘要:
利用几何光学方法对轴棱锥产生近似无衍射光进行分析,给出最大无衍射距离的几何表达式.利用光学设计软件ZEMAX对产生近似无衍射光的光路进行追迹,并模拟横向光强分布.通过几何分析、软件模拟及实验验证,讨论光束半径和轴棱锥底角对最大无衍射距离的影响.研究结果表明,最大无衍射距离随入射光束半径的增大而增大,且近似成正比; 而最大无衍射距离随轴棱锥底角增大而减小,且近似成反比.
Abstract:
In this paper,non-diffracting beam generated by the axicon was analyzed using geometrical optical method and the expression of the maximum non-diffracting distance was given.The non-diffracting beam was traced using the optical design software ZEMAX,and the transverse optical intensity distribution was also simulated.The effect of the beam radius and the base angle γ of the axicon on the maximum non-diffracting distance were discussed through the geometric analysis,software simulation and experiment.Results show that the maximum non-diffracting distance increases with the increasing of beam radius R,and almost proportional with the R; however the maximum non-diffracting distance decreases with the increasing of the base angle γ of the axicon,and inverse proportional with the γ.
