摘要：

In this Letter, we theoretically and experimentally demonstrate a new method to generate tunable orbital angular momentum (OAM) by continuously changing the angle of linear polarization of the input light. We use the Fourier series of left- and right-hand projections to prove that the average OAM smoothly varied from l = -1 to l = 1 with the angle of LP of input light changing from 0 to pi, which is fulfilled by an electrical polarization controller.
