Orbital angular momentum of an arbitrary axisymmetric light field after passing through an off-axis spiral phase plate
We obtain a simple formula for the relative total orbital angular momentum (OAM) of a paraxial light beam with arbitrary rotationally symmetric complex amplitude passed through a spiral phase plate (SPP) whose center is shifted from the optical axis. The formula shows that the OAM equals zero if the...
