Why phase data in NSC is only available with rectangle detector and how it's calculated

Hi Jimmy,
Different detector has different functions, currently is the rectangle detector can be more suitable for handling this data. Different detector has different functions, currently is the rectangle detector can be more suitable for handling this data.
For NSC analysis, OpticStudio uses ray tracing to determine optical paths and energy distributions. OpticStudio accounts for the phase along the ray, and this allows for computation of some interference and diffraction effects. However, it is important that the user understand what assumptions the model makes and how these assumptions affect the accuracy of the results.
When a ray strikes a detector, OpticStudio computes the real and imaginary parts of the electric field by using the intensity and phase of the ray referenced to the center of the pixel struck. The real and imaginary parts may then be summed for many rays that strike the same pixel. OpticStudio also sums the intensity (amplitude squared) for each pixel.

Thanks Sean, this makes sense. It explain why two rays has the same optical path can have different phase. Are phase the fields the only output that’re referenced to the pixel center?
