We demonstrate the reconstruction of a vector Bessel beam after propagation through an obstruction. Not only does the spatial profile of the optical field reconstruct, but we show that its polarization profile also possesses this self-healing characteristic. We experimentally verify this new attribute with the use of radially and azimuthally polarized Bessel beams. By being able to extend this self-healing nature to an additional degree of freedom, in the case of polarization, this will advance the applications of Bessel beams in areas such as optical trapping and quantum entanglement.
