In this experiment we use the diffraction set of the previous experiment but we add a WebCam that accumulates electrical charges in the cells of its CCD.
We set the WebCam to capture a few frames per second and stretch the exposure time to the maximum, this can be done for example by using our applications VideoInput, VideoInspector, MicroVideo, MicroViewer O VideoRecorder. Perhaps the most suitable is VideoInput which could also count the number of pixels illuminated in the various areas and roughly estimate the number of photons based on brightness.
Not all WebCams are adjustable up to one frame per second, some only go up to three and others only up to five (open the “Format Panel” to see its limits). But they will all go equally well because the number of photons that are collected is always many billions even with very short exposure times..
At the end of the exposure time the accumulated electrons are approximately counted by the camera electronics and transferred to the PC with a pixel array.
At this point someone "observes" the result, you don't "observe" it, or maybe you look at it after a month, nothing changes. We are not what quantum defines as an "observer" and there are no paradoxes like that of Schrodinger's cat, because the observation has already taken place in the camera.
The "observation" has already occurred every time the photons hit the camera's CCD chip and turned into electrons, increasing the electric charge at the hit point (pixel).
Each photon decided for itself which direction to go and where to hit the screen. His choice was not determined by previous conditions (hidden variables). Other more complex experiments and Bell's inequalities have proven this time and time again.
However, it cannot be doubted that each photon has chosen its own trajectory and we also observe that the probability with which they have chosen follows some statistical rules and that therefore many of them have behaved in the same way and have created bright points while very few have chosen. the trajectory that led them to a dark area.
However they chose.
Each photon has chosen whether to go in one direction or another.
There is therefore no need to field oddities such as the superimposition of states.
What matters to us who live in the macroscopic field is the overall result, that is, the probability of the occurrence of the various trajectories, and it makes no sense to ask how each single photon decided its trajectory nor does it make sense to imagine that it was in a superposition of states which then collapsed into a specific trajectory.
Each photon, in absolute freedom, without his choice being "determined" by anything else, has chosen its trajectory.
Hence the sophisms like “we can say that he chose A or B ?Are nonsense questions. The photon made a choice without any doubt, so we can certainly say that each of them has chosen trajectory A, or the trajectory B, or C. It doesn't matter whether or not we know what this trajectory is, that we can measure it, whether it is a wave function that has collapsed or whether it is something else. But there is no doubt that each photon is its own choice, somehow, he did it.
