Optical vortices, or phase singularities, are places in a scalar optical wave field where the phase is not defined. Within any beam cross-section they are observed as points of darkness. However, in 3D, these singularities are lines of darkness embedded within the light. The topologies of these dark lines can be imaged by finding the phase singularities in successive cross-sections.
