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.
