I've been thinking about the double slit experiment - the one with single photons going thru two slits forming an interference pattern never the less.
Now, one thing i was unable to find clarification for is the claim that placing a detector even in just one of the slits to find out thru which slit a photon passed will result in the disappearance of the interference pattern.
The question is - how does such detector work?
How can one detect a photon without destroying it?
