Figure 4
From: Gear-like rotatable optical trapping with radial carpet beams
The same patterns and trap images of Fig. 3 when a stop circular aperture was used before the L1 lens shown in Fig. 2. The laser power in each individual trapping spot at the sample is indicated in the second column. See also Visualizations 1 and 2 that they show tapping and annular rotating of the trapped particles.
