Understanding the Detector Polar

The Detector Polar object stores the intensity data from NSC source rays that strike it. The Detector Polar is spherical in shape but the resulting data distributions in the angular domains are displayed in 2D. And this point can cause confusion.
The aim of this article is to explain clearly how OpticStudio maps rays striking 3D sphere onto a 2D intensity plot. It also gives some details on the conventions used in OpticStudio.
