New Rotational Doppler-Effect

Authors: U. Kayser-Herold

By oblique reflection of circularly polarized photons on a rotating cylindrical mirror the frequency of the reflected photons is shifted against the ferquency of incident photons by nearly twice the rotational frequency $n$ of the mirror: $\Delta \nu = 2\hspace{2} n \hspace{2}\sin \alpha$, where $\alpha$ is the axial angle of incidence. $\Delta \nu$ can be substantially enhanced by multiple reflections between counter-rotating coaxial mirrors.
