From: Gear-like rotatable optical trapping with radial carpet beams
(a) CCD-measured center of the mass trajectory and (b) position distribution of a trapped 2.54 μm silica bead during a time interval of 10 mins. (c, d) show the corresponding power spectra in x and y directions, respectively. The inset shows locations of four selected traps in the radial carpet pattern with 10 main spots, used for calibrating the trapping stiffness. Distribution of radial position (e) and tangential position (f) of the trapped particles in positions 1–4. (g) Position distribution of the similar trapped particles in polar display.
