摘要:
研究高斯型光谱的完全空间相干光经菲涅耳波带片后,远场轴上点的光谱奇异现象.结果表明,在相位奇异点处,高斯型光谱一分为二,出现光谱开关现象.在相位奇异点附近,一些点处的光谱发生蓝移,而另一些点处的光谱发生红移.这些光谱奇异现象与观测点位置有关,光谱开关总是发生在光强为极小值处.分析和比较几种菲涅耳波带片的光谱奇异现象,以及其光强分布情况.
Abstract:
Spectral anomalies taking place at axial points of Fresnel zone plate illuminated with a fully spatial coherent Gaussian beam,are studied in this paper.The results show that,at the points of phase singularities,the Gaussian spectrum is split into two lines,meanwhile the spectral switches occur.In the neighborhood of the singularities,the spectrum is redshifted at some points,and blueshifted at others.These spectral anomalies are related to the position of the observation point.The results still show that the spectral switches always occur at the points with minimal values of intensity.After that,comparisons of spectral anomalies and the intensity distributions of various kinds of Fresnel zone plate is also made.
