Say you shoot electrons through a single circular aperture, and shine light across it to use Compton scattering to detect particle position.

The detector screen is a circle a few inches across. Obviously, it will have no diffraction pattern on it. It will have the classical 'scattering' spread of light across its surface.

Now we place another screen behind the first one. Since the first screen is small enough to have light hit the edges, will there be a diffraction pattern behind it on the second screen? Will the poisson spot be there?
