  Polarisation holography generally demands polarisation-sensitive holograms
for reconstructing either polarisation-multiplexed holographic images or
polarisation-sensitive image channels. To date, polarisation holography is
underpinned by the Jones matrix method that uses birefringent holograms,
including ultrathin metasurface holograms, limiting the polarisation control to
orthogonal polarisation states. Here I introduce a novel concept of vectorial
wavefront holography by exploiting the wavefront shaping of a structured vector
beam. I will show that a phase hologram can be used to tailor the polarisation
interference of a vector beam in momentum space, creating arbitrary
polarisation states that include but not limited to the linear, circular,
azimuthal, and radial polarisations. This opens an unprecedented opportunity
for the multiplexing generation of arbitrary polarisation distributions in a
holographic image. The demonstrated vectorial wavefront holography offers
flexible polarisation control without using birefringent optical materials,
which may find applications in polarisation imaging, holographic encryption,
holographic data storage, multi-view displays, holographic Stokesmeter, and
polarimetry.
