What's The Difference?

OK, I have two figures here for you:

A.


B.

Other than the orientation and the pixel density, can you tell what is what in these two, and what are the differences?

No?

What if I tell you that one is a 2-slit interference experiment using single electrons, while the other is a 2-slit interference experiment using single photons. Can you tell which is which?

You are not at fault if you can't, because I won't be able to either, just from looking at the figures. Figure A is the single-photon interference experiment, while Figure B is the single-electron interference experiment (G. Matteucci et al., Eur. J. Phys. v.34, p.511 (2013)). The effects look the same for both.

    I cant imagine how is it possible to make a interference experiment with photos ;-)
