Dear I Chavdarovski,

Whenever you want to detect which slit the photon or electron is passing through, you loose the double slit interference pattern.

This is the same statement as before.

Whatever detector you use, once the photon or electron is detected by the detector , the original path or the propagation is lost and the pattern vanishes.

Thanks

There are so many options to detect photons and electrons, such as chemical detectors (film), semiconductor detectors (photo diodes, CMOS and CCD detectors). In case of visible photons, human eyes can do the same job.

Not sure what Einstein or Bohr had said about the double slit experiments, but there are sure plenty of discussions almost everyway. Enough has been said, and wikipedia records some important explanations.

Not very much recent progress on the double slit experiment, but I can offer some new considerations to help enlighten the analysis of double slit experiment. I believe that photons and electrons will not interact with the open slits but rather the materials of the blocking part of the slits. This can be done by a thought experiment. Reducing the double slit smaller and smaller, bring it down to a double slit consisting of just a few electrons or atoms, then the double slit experiments become a particle scattering experiment, the scattering will become Compton scattering or electron scattering with electrons and atoms. This new consideration will involve the conservation of energy and momentum that most theories about double slit experiment have basically overlooked. The new consideration is not hard to prove experimentally either. Just pick up photons after the double slit at different exit angles, and analyze their energies by interference, then we will see that the photons have changed their energies after the double slit although very slightly. This result is very much certain to hold true, because if it fails, then Compton or particle scattering will need modification because Compton and particle scattering is simply the extreme case of double slit experiment.

See Afshar Experiment on wikipedia. This references several papers and offers a rebuttal to the claim.

Any experiment that places a detector (any bit of matter) between the mask with the slit and the screen is going to be meet with a challenge of Quantum Interpretations such as Copenhagen. But then Quantum interpretations do not explain several experiments that reject (including interference experiments) the the Huygens- Fresnel model of light. That is the wave nature of light that the double slit experiment was/is supposed to prove. But I notice you seem to reject the wave nature of light in your question - refer to photon or electron (particle models of light).

see for these several experiments

Dear Sydney Ernest Grimm,

high temperature magnetized plasma generally does not exhibit quantum behavior. My question was in a general connection to classical physics , how does the detector collapse the function. If particle detection is in effect collision, what happens to the classically measurable quantities. I will post a separate question about this.
