WebApr 11, 2024 · Fig. 2 shows the OAM of a non-zero radial index LG beam at different aperture, the calculation parameters are: l=3, p=5, w 0 =3mm, λ=633nm. The theoretical results are based on Eq. (5), the integral upper limit in the numerator is replaced by the corresponding aperture radius (the corresponding ring number obtained), and the … WebIn geometric optics, the paraxial approximation is a small-angle approximation used in Gaussian optics and ray tracing of light through an optical system (such as a lens ). [1] [2] A paraxial ray is a ray which makes a small angle ( θ) to the optical axis of the system, and lies close to the axis throughout the system. [1]
