Im having difficulties showing the spatial distribution of optical intensities observed in the far field region, due to fraunhofer diffraction.
I have an arpeture function that is in the form of a delta functon, and i understand that with the delta function situated at the origin the observed intensity in the xy plane is the 2d fourer transform of the delta function.
However, how does this vary if the delta function moves away from the origin, and specifically with 2 delta functions equidistant from the origin that are in opposite quadrants?
Any input would be appreciated
