干涉孔径角与光源宽度的推导和估算

Inferential Reasoning & Estimation of Interference Opening Angle, Photo Source Width

通过对杨氏装置中干涉合成光强的计算,得出其干涉条纹的可见度是零阶球贝塞耳函数,根据sinC函数及可见度的性质对干涉孔径角和光源的宽度进行了估算和推导。

The visibility of its interference fringe is the zeroth order ball besser ear function, which can be obtained by the computation of Yang＇s Installment interfering the synthesis luminous intensity. The estimation and the inferential reasoning can be conducted according to the sinC function and the visibility nature
