The diagram shows a typical optical experiment.

The optical Bloch equations enable a transparent analysis of several nonlinear optical experiments.

The diagram shows a typical optical experiment of the two-channel kind for which Alain Aspect set a precedent in 1982.

He performed optical experiments with camera obscura just decades after Ibn al-Haytham was the first to do so.

It is of great importance in optical experiments.

Both are widely used in optical experiments that use lasers as a light source.

Intralipid is also widely used in optical experiments to simulate the scattering properties of biological tissues.

It was later shown that all first-order optical experiments must give a negative result due to this coefficient.

In Bell test experiments one problem is that detection efficiency may be less than 100%, and this is always the case in optical experiments.

With only one exception, all Bell test experiments to date have been affected by this problem, and a typical optical experiment has around 5-30% efficiency.
