Abstract

We report experimental observation of a transverse shift of the centre of gravity of partially reflected optical beam having non-zero orbital angular momentum. The results are in reasonable agreement with the theoretical predictions. Possibility of using such shift for measurement of orbital angular momentum state of photon is discussed.
