  Wave propagation properties in a medium are fundamentally affected when this
medium is moving instead of at rest. In isotropic dielectric media rotation has
two noteworthy contributions: one is a mechanically induced circular
birefringence which materialises as a rotation of the polarisation, the other
is image rotation which corresponds to a rotation of the transverse structure
of a wave. Here we review the effect of rotation in a magnetised plasma. We
first show that the mechanical effect of rotation on polarisation is in a
magnetised plasma superimposed onto the classical Faraday rotation, and that
failing to account for this new contribution could lead to errors in the
interpretation of polarimetry data. We also demonstrate that image rotation is
recovered in plasmas for a number of low-frequency magnetised plasma waves
carrying orbital angular momentum, and that this phenomenon holds promise for
the development of new rotation diagnostic tools in plasmas.
