本文报道了具有非零轨道角动量的部分反射光束的重心横向移动的实验观察。结果与理论预测基本一致。讨论了利用这种位移测量光子轨道角动量态的可能性。
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.
