Resumen
A technique for determining the topological charge of supercontinuum optical vortices is presented. Spatial dispersion is compensated with a unique double-pass arrangement, and charge is consistently measured across a wide range of colors by observing diffraction through a triangular aperture. © OSA 2012.
