My layman's understanding of one aspect of the wave/particle duality is that when we attempt to detect wave behavior we observe wave behavior, and when we measure to detect particle behavior we observe particle behavior.
The way that I understand the double-slit experiment is that the detector behind the slits is detecting particle hits, be they photons of light or what we classically describe as particles. So, I'm wondering if there have been experiments which use an array of antennae to observe the wave behavior after passing through the slits, rather than a particle/photon detector.
I do understand that the wave function is mathematical tool that represents and predicts quantum behavior, and it is uncertain whether it describes physical matter. Since there is an issue of wave behavior, I'm interested in what we can learn about it.
