Has anybody ever placed several double slit "cards" in parallel?

I wonder what might happen if we lined up about six cards one behind the other, and made every card in the sequence a little larger as they fade back towards some termination plate.

 

1) Would the wave catch the edges of the larger cards and record several electron positions? If so this might prove that what we are actually seeing, in the original experiment, is not the electron that was fired but a clone produced from the wave.

 

2) What might happen if we put the polarizing film on the fourth or fifth card back?

 

Is there any group doing different variations of this experiment?

 

I'd like to see what might happen if the card was round and spinning very fast. That might be interesting.

In parallel? Or in series? Because that sounds like you mean in series — one after another.

 

The answer is (sort of) yes. You can make an interferometer with a series of diffraction gratings (it's a Mach-Zehnder topology)
