中文摘要	研究了多色空间完全相干光经过环形光阑衍射后在近场出现的光谱变化,并给出了详细的数值计算结果和具体实例.结果表明,在近场强度为零的奇点附近也同远场一样发生了光谱显著的变化,即奇点一侧光谱发生红移,奇点另一侧光谱发生蓝移,而在奇点处则发生了红移和蓝移之间快速的转变.研究表明,中心拦截比的变化对近场的这种光谱变化有很大的影响,并随着中心拦截比的增大,近场逐渐过渡到远场.; The singularity changes and spectral behavior of polychromatic spatially fully coherent light diffracted by an annular aperture in the near field were studied.Detailed numerical calculation results were presented and illustrated.It was shown that the spectral anomalies took place in the vicinity of singularities in the near field,namely,the spectrum was red-shifted at some points,blue-shifted at others,and was split into two lines with equal height elsewhere,and this kind of spectral change depended on the central obstruction ratio ε and axial distance z.It was found that,with the increasing of the central obstruction ratio ε,axial singularities would shift to the aperture and at the off-axial positions new singularities would appear and split.With the further increasing of the central obstruction ratio,the near field changed to the far field finally.; 【作者单位】集美大学理学院；【作者英文名】FU Xiao-ming,CHEN Jin-tai,TANG Li-hua,HUANG Hong-wei(School of Sciences,Jimei University,Xiamen 361021,China)
