Real-time calibration of multiple vector beam traps consisting of radial, linear and azimuthal polarization states. At some set stage velocity the weakest radially polarized trap (bead 1) results in the bead escaping while the beads in the stronger traps (beads 2 and 3) remain trapped. Arrows show the direction of motion of the stage while the particle in the white dotted circle serves as a stationary reference. See Supplementary Information for the video file.
