Optical systems and spatial frequencies

We analyse the meanings of spatial frequencies when diffraction effects in optical systems illuminated by monochromatic light are described. The field distribution in any plane of the system can always be considered as a Fourier expansion such that each Fourier's component travels in a directio...
