Therefore, the complex number control parameter at A

Therefore, the fringe visibility at the receiver B screen at points x' can be computed from the local cross terms
(A1|A2)(B1|x')(x'|B2) + cc
Let n1 = n2 = n equal intensity at the transmitter A slits.
(A1|A2) ~ exp{ - n[(1 - e^i(@1 - @2)]} + exp{ - n[(1 - e^-i(@1 - @2)]}
& = @1 - @2
(A1|A2) ~ exp{ - n[(1 - cos& - isin&)} + exp{ - n[(1 - cos& + isin&)}
~ e^-n(1 - cos&){e^insin& + e-insin&}
~ e^-n(1 - cos&)2cos(nsin&)
as n increases we want & approaching zero to prevent the receiver interference terms from getting too small.
~ 2e^-n&^2/2cos(n&)
