Abstract
The frequency shift imparted to a light beam possessing angular momentum when the beam is rotated with respect to the observer and for light that is both circularly polarized and has an azimuthal phase structure was investigated. The light consequently possesses orbital angular momentum per photon in addition to the intrinsic angular momentum per photon. It is shown that the shift may be readily understood in terms of the shape of the phase fronts of the beam. The energy exchange between rotating half-wave plates and light beam with intrinsic spin and orbital angular momentum may also be interpreted as manifestations of the rotational frequency shift. The changes in the frequency for an arbitrary rotating light beam was also calculated.
