Is there real experimental video footage (not animation) of a double-slit experiment showing the interference pattern disappearing after turning on which-path detectors at the slits?
Has such a video, with before and after comparison, ever been recorded and published?
Edit for clarity:
What I’m hoping to find is a video that compares two accumulated patterns of single particles passing through slits - one pattern when we don’t know which slit each particle went through, and one when we do.
Edit 2:
Something like this: https://youtu.be/_MpvDAQrKbs, but with a second run where which-path detectors are enabled at the slits, so we can determine which slit each particle passes through. This would cause decoherence of them, force wavefunction collapse and, as a result, change the interference pattern in real time. It doesn't have to be photons, can be any particle. Of course, I may also be misunderstanding something in this chain of reasoning.
