  Laser remote sensing represents a powerful tool that enables the accurate
measurement of the speed of moving targets. Crucially, most sensing techniques
are 2-Dimensional and only enable direct determination of the speed along the
line of sight. A disadvantage that is very often overcome using two-dimensional
techniques that in many cases are hard to implement and expensive. Here we put
forward a novel 3-Dimensional technique that enables the direct and
simultaneous measurement of both, the speed and the spin rate of cooperative
targets. This technique is based on the use of complex vector light beams,
whose polarization and spatial degree of freedom are coupled in a non-separable
way. We present experimental evidence of our technique by performing a
laboratory proof-of-principle experiment.
