This question is motivated by recent experiments in QM entanglement. consider the following "simple/ simplified" classical analog of Bells experiment. it has a laser, a standard beamsplitter reflecting light in 2 directions "left/ right", and 2 polarizing beamsplitters, 1 at each left/ right arm. This creates 4 separate rays fed to 4 light detectors. 1 of the arms has a rotation angle relative to the other "θ".
Now consider a twist on the detection. The detectors measure light intensity, but convert it to binary on/off measurements ("pulses") based on a threshhold value T.
There is another twist. There is a motorized rotating polarizer screen in front of the laser prior to the 1st standard beamsplitter. It rotates at a constant speed.
The standard correlation coefficent for the Bell experiment is E(θ) = R++ + R-- - R-+ - R+- (where Rs are coincident pulses at opposite ends as in standard experiments).
In this experiment, E(θ) is calculated based on the detector threshhold measurements over short time Δt, counted/ integrated over long time scales/ many repeated measurements.
what is the formula for E(θ) (calculated using classical physics)?
note: can foresee there are some hidden subtlety(s) in calculating this formula.
