Query: Corrected knife-edge-based reconstruction of tightly focused higher
  order beams   The knife-edge method is an established technique for profiling of even
tightly focused light beams. However the straightforward implementation of this
method fails if the materials and geometry of the knife-edges are not chosen
carefully or in particular if knife-edges are used that are made of pure
materials. In these cases artifacts are introduced in the shape and position of
the reconstructed beam profile due to the interaction of the light beam under
study with the knife. Hence, corrections to the standard knife-edge evaluation
method are required. Here we investigate the knife-edge method for highly
focused radially and azimuthally polarized beams and their linearly polarized
constituents. We introduce relative shifts for those constituents and report on
the consistency with the case of a linearly polarized Gaussian beam. An adapted
knife-edge reconstruction technique is presented and proof-of-concept tests
demonstrating the reconstruction of beam profiles are shown.
