准单色光照射轴锥镜的衍射特性

The non-diffracting beam generated by an axicon has a small central spot diameter and a long non-diffracting distance of transmission,so the depth-of-focus of non-diffracting imaging system can be extended as well focalization is unnecessary.

利用轴锥镜产生无衍射光,无衍射光束具有中心光斑直径小且传播距离远的特性,将无衍射光理论与技术应用到成像系统中可加大焦深且无需调焦。

The axicon that can image a point into a line segment along the optical axis can be used to extend the depth-of-field of an imaging system,and the imaging theory was explored.

根据轴锥镜的线焦特性,阐述了基于轴锥镜的大景深成像系统的基本原理。

For requriement of plasma diagnostic system in inertial confinement fusion(ICF) drivers,simple lens which can be substituted for logarithmic axicon is designed by nonlinear-phase fitting method.

针对惯性约束聚变(ICF)激光等离子体诊断系统应用的需求,提出一种采用非线性相位拟合法设计单透镜代替理想对数轴锥镜的方法。

Staring from Fresnel diffraction integral,we deduced the optical intensity distribution in the Fresnel zone of the diffraction field of the annular-aperture lens axicon.

结果表明,光谱半宽σ小的多色高斯光束照射透镜轴棱锥时,不同观察面的光强分布均为J20的形式。
