Paper Abstract

We examine the revival of the nondiffracting vortex beam after its interaction with the 2D obstacle. We verify that the intensity profile, the phase topology and the spatial distribution of the orbital angular momentum of the beam transmitted through the obstacle regenerate to the initial form during further free-space propagation. The healing effect appears even if the obstacle possesses the helical phase and the interaction is accompanied by the exchange of the orbital angular momentum. The effect is applicable to the design of the light powered micromechanical rotors.
