Thanks Arjen for making this clear...I hope this is "real"
fact...because when I read the book "the fabric of cosmos- by Briane
Green " the understanding that I got was otherwise where the detection
of electron at any slit in the double slit experiments through indirect
techniques (where the motion of the electron was left undisturbed,
through the use of some reflectors etc.,) showed NO interference
eventhough the electron was left undisturbed. There are some
experiments that are described in this book to demonstrate this.

That are interesting experiments. Could you tell me more about them? (I
also ordered the book.) It seems to me hardly understandable to detect
an electron at a slit leaving that electron undisturbed, even through
indirect detection. But why not;-)

see it, a photon has disturbed it*
