%Example of how an optical spectral line is mapped into the propagation angles, and the corresponding spatial projection, for non-paraxial regime (high angles)

% In short, the radial components of frequencies and angles are related with radial_frequencies = sin(radial_angles), 
% and the radial components of the spatial projection are related with radial_angles=atan(radial_spatial_projections).

% For small angles these trigonotmetric relations are just proportional relations (in paraxial aproximation).

% I will be surprises id there are not mistakes/bugs. Comments to @miguelscilight.
