What does "particle/wave detector" mean?

How does it detect? Is it a double slit?

I have no idea how the detector that would allow it to pass through would work. As for the other detectors used in this experiment, the measurement devices at the end result in a similar pattern to the double slit when it's a wave, which is how they distinguish between wave and particle.
Let's say that for the purpose of this thought experiment, it uses the same mechanism but lets the particle pass through.

So, I'm thinking about it. It looks like they're talking about the polarization of the light, not the position/momentum.

So these devices are measuring the polarization distribution.

So, presumably the beam splitter splits "x and y" polarization states. Say that it sends the x polarized light on the top half, and the y polarized light to the bottom half...

Then what you should get if you measure the photon where the purple thing is just x polarized light with uncertainty that corresponds to the properties of the splitter itself. (So a classical result).
So, at the point we measure

It's not that light decides to be a particle or a wave. It's not a particle or a wave - light is light.
Light has properties that we interpret as wave-like and particle-like. That is, it behaves both, like we know from particles and from waves. And depending on how we measure it, how we look at it, or in other words, at which of its properties we look, it seems to be one of them.

If you want to rephrase it as momentum/position,
Instead of talking about "x vs y" polarization states, you can think about "particles where i know the position vs particles where i know the momentum", and replace the measuring devices with double slits, and the experiment is essentially the same.

Thank you for helping clear up what I meant
