From: Which-way identification by an asymmetrical double-slit experiment with monochromatic photons
”Which-way” identification by sizes of the central bands \(D_m^{int}\): Shorter spectrum regards \(I_1\)-photons passing through the wide-slit. \(I_1\)-photons are absent in the first main minima (indicated by yellow arrows) of \(D_1^{dif}\) at \(\alpha _1\). Contributions \(I_1\) and \(I_2\) are integrated between their corresponding main minima at \(x_i=\pm x_{1}\) (blue arrows). Experimental luminance distributions in Column (II) for directions at \(\alpha _2\) and \(\alpha _5\) after correction of interference fringes with \(j=5\div 7\) (red lines in yellow ellipses) fit well the Fraunhofer approximation in the vicinity of the main minima.
