Rotating wavefields are characterized in order to describe the propagation of this class of propagation invariant optical fields (PIOFs). As the use of rotating wavefields for momentum transference in research applications has only recently been reported in the literature, experimental setups will aid in determining the feasibility of such applications of rotating wavefields in particular and PIOFs in general. The present work is devoted to Bessel PIOFs and in particular, to a generation method based on interferometric techniques. Rotating Bessel wavefields are experimentally observed and characterized.
