We propose a realistic scheme to detect topological edge states in an opticallattice subjected to a synthetic magnetic field, based on a generalization ofBragg spectroscopy sensitive to angular momentum. We demonstrate that using awell-designed laser probe, the Bragg spectra provide an unambiguous signatureof the topological edge states that establishes their chiral nature. Thissignature is present for a variety of boundaries, from a hard wall to a smoothharmonic potential added on top of the optical lattice. Experimentally, theBragg signal should be very weak. To make it detectable, we introduce a"shelving method", based on Raman transitions, which transfers angular momentumand changes the internal atomic state simultaneously. This scheme allows todetect the weak signal from the selected edge states on a dark background, anddrastically improves the detectivity. It also leads to the possibility todirectly visualize the topological edge states, using in situ imaging, offeringa unique and instructive view on topological insulating phases.
