Abstract In this study, the change in the angular momentum of a vortex beam after reflection from a relativistic flying mirror is investigated. This change is determined by performing full three-dimensional particle-in-cell simulations. The results confirm that the spin angular momentum and linear momentum carried by the reflected beam are collinear. In addition, we show that the orbital angular momentum is not collinear with the linear momentum carried by the reflected beam owing to the Doppler effect.
