From: Which-way identification by an asymmetrical double-slit experiment with monochromatic photons

A relative luminance of fringes in \(x=\pm x_1\) to their neighbors vice-versa horizontal directions of the laser beam: A strong correlation of Experimental ratio \(R(7/6)=I(min.)/I(6)\) with Fraunhofer approximation curve is consistent with the increasing contribution of \(I_2\)-photons while going against the decreasing \(I_1\).
