The path of photons can be (almost) reconstructed in a double slit experiment!

Of course, I predicted this would be possible about a year ago:

It may be possible to construct sufficiently delicate measurement techniques so as not to destroy the interference. The Copenhagen Interpretation says this is not possible but I'm not so sure it isn't.

EDIT oops at least one thread already posted on this experiment https://www.physicsforums.com/showthread.php?t=503861
