Kartazion Posted October 11, 2020 Share Posted October 11, 2020 It's been a while since I wanted to reproduce the double-slit experiment by placing photosensors on the reception screen. The question is already how and by what process are the impacts marked on the screen? Link to comment Share on other sites More sharing options...
Markus Hanke Posted October 12, 2020 Share Posted October 12, 2020 The outcome of the experiment does not depend on the particulars of the detector apparatus, or even on the layout of the setup itself; it depends only on what information is accessible to the experimenter. So long as the only accessible information is position and time of each individual detection event at the receiver device, a large ensemble of such events will always form an interference pattern. On the other hand, if any form of which-path information is available from the setup, then there will be no interference pattern. 1 Link to comment Share on other sites More sharing options...

It is precisely the interest of the photosensors , to be able to study the interference according to the behavior of the experimenter. Link to comment Share on other sites More sharing options...

You can independently test if the photosensors depend on the behavior of the experimenter. (if being near the circuit changes the capacitance and thereby changes the efficiency, for example) You don’t need to do an interference experiment. In fact, you would have to test this independently, if you want a valid experiment. Only then could you test the effect on the interference. Which, as Markus has noted, would be unaffected Link to comment Share on other sites More sharing options...

This falls under the umbrella of good experimental technique. Proper grounding and insulation so there is no electromagnetic interference. If you think there’s some other effect, you need to be more specific about the interaction you think is in play. Link to comment Share on other sites More sharing options...

No. I don't want to test psychokinesis. Why do you say that? I only want to study the behavior of the electromagnetic wave. For this I need to understand the interference in relation to the particle. But the particle is a wave. I think I find a compromise in Electromagnetic radiation. Edited October 12, 2020 by Kartazion Link to comment Share on other sites More sharing options...

Kartazion Posted October 13, 2020 Author Share Posted October 13, 2020 I wish to study the transition from the interference pattern to a corpuscular impact pattern, and vice versa. Was this transition already studied theoretically or experimentally? The photosensors allow us to understand if there would be a pattern transition procedure order Link to comment Share on other sites More sharing options...

The statistical distribution of many individual hits on the detector. 16 hours ago, Kartazion said: The experimenter observe it with a captor? The which-path information does not need to be physically observed, it only needs to be accessible in principle, for there not to be an interference pattern. 1 Link to comment Share on other sites More sharing options...

The photosensors allow us to understand if there would be a pattern transition procedure order So it’s not that you want to study EM. What is this “transition”? The detection is both - you detect particles, and it follows the interference pattern. The more you detect, the better your statistics get (to first order, anyway) Link to comment Share on other sites More sharing options...
