Using axicon-based optical devices can realize such transormations as Gauss beam into a diffraction-free Bessel beam,solid beam and annular beam converting eachother.
应用旋转棱镜和组合光学系统能够将高斯光束变换成“无衍射”贝塞尔（Ｂｅｓｓｅｌ）光束，并能实现实心和环状光束的相互变换。
2) Annular flattened beams
环状平顶光束
3) annular Gauss beam
环状高斯光束
4) partially coherent annular beam
部分相干环状光束
1.
Based on the extended Huygens-Fresnel principle, the analytical expression for the spectral degree of coherence of partially coherent annular beams propagating in atmospheric turbulence is derived by using the quadratic approximation of Rytov\'s phase structure function, and the spatial correlation properties are studied.
基于广义惠更斯-菲涅耳原理,并采用Rytov相位结构函数二次近似的方法,推导出了部分相干环状光束通过湍流大气传输时,其光谱相干度的解析公式,并研究了光束的空间相干特性。
5) toroidal micelle
环状胶束
6) shape of beam
