In the Afshar experiment, a grid of thin wires is placed just before the lens on the dark fringes of an interference pattern.
Notes on verification
Wikipedia and multiple independent arXiv physics papers consistently describe the same experimental setup: thin wires placed at dark fringes just before the lens.
