You mean this?

Hmmm... Afshar's experiment is a bit like the standard textbook two-slit experiment but with wires in the dark bands, then remove the screen and adding interferometer arms to keep the particle's superposition until a much later detection.

The "detection" of the interference pattern by not interacting with the wires involves... er... no interaction, so it doesn't sounds like a true violation of complementarity to me.
