Visualization 1 | Retrieved spatiospectral intensity (a) and phase (b) of the same ultrashort optical vortex (l = +2) measured using the algorithm 2D4Quad and measuring the spatial spectrum of the ordinary beam with two different walk-off crystals: BBO (a1,b1) and Cal

Visualization 2 | Retrieved spatiotemporal intensity (a) and phase (b) of the combination of two delayed ultrashort optical vortices with different OAM (l = +2 and l = 0) using the Calcite walk-off crystal. (Associated with Fig. 7 in the manuscript). The retrieval was

Visualization 3 | Simulated spatiotemporal intensity (a) and phase (b) of the combination of two ultrashort optical vortices with different OAM (l = +2 and l = 0) with a delay of 63 fs. (Associated with Fig. 8 in the manuscript).
