  We describe an experimental setup for imaging topologically protected Floquet
edge states using ultracold bosons in an optical lattice. Our setup involves a
deep two dimensional optical lattice with a time dependent superlattice that
modulates the hopping between neighboring sites. The finite waist of the
superlattice beam yields regions with different topological numbers. One can
observe chiral edge states by imaging the real-space density of a bosonic
packet launched from the boundary between two topologically distinct regions.
