Note that this derivation is valid … WebGeometrical optics (ray optics) describes light propagation in the form of geometric rays. Here, the paraxial approximation means that the angle θ between such rays and some reference axis of the optical system always remains small, i.e. ≪ 1 rad. Within that approximation, it can be assumed that tan θ ≈ sin θ ≈ θ.The evolution of beam offset …
