In the question Double Slit experiment with just one photon or electron, one of the answers says

There have been experiments recently where one can detect which the slit the particle went through and still the interference pattern appears.

This had 6 votes. Is it correct? If you put a detector to find out which way the particle went through won't that destroy the interference?

    $\begingroup$ I remember reading that (and sadly forget where). The slit determination was of course an "indirect" observation. $\endgroup$ – Carl Witthoft Nov 20 '13 at 19:26

    $\begingroup$ The most recent link in the wiki paragraph I linked to in my answer is behind a paywall newscientist.com/article/… . Not even the names of the authors are given. I remember that they used a difuse source method to reach the result of knowing which slit it came through, but cannot find an article $\endgroup$ – anna v Nov 20 '13 at 19:43

    $\begingroup$ What about this? arstechnica.com/science/2012/05/… I found it linked as reference 30 in this Wiki article: en.wikipedia.org/wiki/… $\endgroup$ – BMS Nov 20 '13 at 22:08
