摘要：
We produce optical vortices using a computer generated hologram (CGH) having a forked grating. We propose to use free space trajectory of the vortex produced for assigning sign to topological charge associated with the vortex. We find experimental trajectory of the vortex that is matched with theoretical trajectory for negative as well as positive charge obtained with Collins integral formalism for vortex propagation. This match is used to determine the sign of the vortex charge unambiguously.
