abstract = "Laser beams with Orbital Angular Momentum (OAM) are revolutionizing optical communication systems, especially for next generation 6G networks. These beams encode information spatially, making precise detection crucial. This research presents methods for determining Bessel-Gauss beam OAM by analysing diffraction patterns through various apertures. By using different aperture shapes to sample the Bessel-Gauss beams and examining the resulting far-field diffraction patterns, we can accurately determine the topological charge of the incoming beam.",
