  Synthetic chiral light enables ultrafast and highly efficient imaging of
molecular chirality. Unlike standard circularly polarized light, the handedness
of synthetic chiral light does not rely on the spatial structure of the light
field: it is encoded locally, in the chiral trajectory that the tip of the
electric-field vector draws in time, at each point in space. Being locally
chiral, already within the electric-dipole approximation, synthetic chiral
light is a highly efficient chiral photonic reagent. Synthetic chiral light
that is locally and globally chiral allows us to selectively quench the
nonlinear response of a selected molecular enantiomer while maximizing it in
its mirror twin at the level of total signal intensities. Synthetic chiral
light that exhibits polarization of chirality allows us to realize a chiral
version of Young's double-slit experiment that leads to enantio-sensitive light
bending. Here we connect these two new concepts and show how one can structure
the local and global handedness of synthetic chiral light in space, and how
these local and global properties are imprinted in the enantio-sensitive
response of the chiral molecules, creating new opportunities for ultrafast,
all-optical and highly efficient imaging of molecular chirality.
