So another answer I got was that mostly electrons are used and something like circuits with current flows can be placed at each slit and detect moving charges.
I wouldn't know how to set that up but it sounds reasonable Probably makes more sense then a camera.

That's a good thing. I'm finding most of the serious discussions I enter around here are knocking me on my ass. All my ideas are being seriously challenged. It sometimes feels like I'm being broken down. But then, that's the starting point for growth, isn't it?
Yeah... I love serious discussions for that very reason. They make you analyze your current ideas. If I think I'm right and can support my beliefs, I'll defend them until proven otherwise. But after much experience with being proven wrong it has lost a lot of sting. I'd rather learn and move forward.
