Alternative Explanation for Double Slit Interference

[vin300]

i think I have an alternative explanation to the double slit.We can assume that the slit surface is not completely smooth,thus a photon may enter these gaps thus allowing for interference in the case of single photon emitter

.. and how does this explain the same type of interference pattern we see in SQUIDs with supercurrent interference, electron interference, neutron interference, etc.. etc? Where are the "surface roughness" there?
