  Vector vortex beams, featuring independent spatial modes in orthogonal
polarization components, offer an increase in information density for emerging
applications in both classical and quantum communication technology. Recent
advances in optical instrumentation have led to the ability of generating and
manipulating such beams. Their tomography is generally accomplished by
projection measurements to identify polarization as well as spatial modes. In
this paper we demonstrate spatially resolved generalized measurements of
arbitrary vector vortex beams. We perform positive operator valued measurements
(POVMs) in an interferometric setup that characterizes the vector light mode in
a single-shot. This offers superior data acquisition speed compared to
conventional Stokes tomography techniques, with potential benefits for
communication protocols as well as dynamic polarization microscopy of
materials.
