Hi
I have some questions and ideas regarding Bohr's double slit experiment which he extended with a Camera as an illustration of delayed choice. I read about it 40 years ago but can't find a reference to it, I'm hoping it wasn't apocryphal but it's consistent with Q-phys as I know it.
The experiment layout.
Imagine a diamond shape, 1 metre each side. The entangled photons are emitted at the 'south' angle, mirrors at east and west and the 'result' screen at north. The east mirror is a half-mirror with a 2 metre extension leading to a potential 'observation point', in this case a camera.
My memory tells me as Bohr ran the slit experiment with the camera:
1) With film - No interference
2) No film - Interference.
Can someone confirm (or deny) this before I go further, as, well I'm sure you know why.
