1. Spatial distribution of light intensity
To deduce the light intensity at any point in space, we need to know the total amplitude of the electric field . The aim here is to detail the reasoning that simplifies the calculation of this amplitude, and which forms the basis of all applications in Fourier optics.
1.1 Total intensity and amplitude of the light wave
Light propagates thanks to variations in electromagnetic potential, which create an electric field
