In a single particle double slit (self-interference) experiment:
the which-way information is got by having the detection instrument (or at-least part of the instrumentation) right next to the slits.To make it easier, Let's assume the following x-coordinates:
at source of photon x = 0
slits are at say x = 10
the final screen (i.e. where the pattern is formed) is at, say, x = 20
The question is:
1. can we detect the photon at x = 15? (i.e. somewhere between the slits and the screen)
if so,
2. would it's location (i.e y-coordinates at x =15) be consistent with self-interference of the wave function? i.e. show an interference pattern at x = 15? and if we were to let it proceed further (after detection) would it just proceed in a straight line and show a blob at x = 20?
thus interference till the time the photon is not detected and no-interference after that for sometime.
i hope i have been able to explain the question accurately, else I will do so in my responses
