This section introduces a model that aims to control the complex drift disturbance of the orbital angular momentum (OAM) vortex beam through the use of a spiral beam. The analytical formula for the correlation function of Laguerre-Gaussian beams under independent drift disturbances is derived, revealing the periodic variations in the intensity distribution, average OAM, and OAM spectrum in the direction of drift disturbance. These findings are supported by consistent experimental results. To further investigate the effect of complex drift disturbances on this type of beam, this section also presents experimental research on vortex beams that have been impacted by cross-correlation drift disturbances
