FFT Vectorial PSF - 2D

This example demonstrates how to use the VectorialFFTPSF class to calculate the 2D PSF of an optical system.

Note: Vectorial PSF calculations are automatically performed when polarization is enabled in the optical system. This accounts for the vectorial nature of the electric field at the exit pupil.
