细丝衍射图样中干涉条纹精细结构的研究

Study of Fine Structure of Interference Fringe on Diffraction Pattern by Filament

在激光束直接照射细丝时，发现了衍射条纹的精细结构。利用细丝衍射光强分布函数对条纹进行了分析，建立了条纹的数学表达式。

Fine interference fringe is discovered on diffraction experiments of filament by meams of Laser beam illuminating directly. The fine fringe which show in diffraction pattern,is analyzed in ration by light distribution function of filament diffraction. Also,its counting fringe expression is established. Study results show that theoretical model is correspond to experiment results completely.
