A wide class of nonuniformly totally polarized beams is introduced that preserve their transverse polarization pattern during paraxial propagation. They are obtained as suitable combinations of Gaussian modes and find applications in polarimetric techniques that use a single input beam for the determination of the Mueller matrix of a homogeneous sample. The class also includes beams that present all possible polarization states across their transverse section (Full-Poincaré beams). An example of such beams and its use in polarimetry is discussed in detail. The requirement of invariance of the polarization pattern can be limited to the propagation in the far field, in which case less restrictive conditions are found and a wider class of beams is obtained.
