FIG. 1.

(Color online) (a) Schematic diagram of the system. (b) The cartoon illustrates the principle of using a modified confocal setup to detect the movement of an object in the direction.

Typical stage positions in the , , and directions as a function of time. The standard deviations are shown on the side. The insets zoom in at the first several millisecond trajectories just before and after the feedback engages.

FIG. 3.

(a) The scattered green light intensity measured by an APD. The arrow indicates the time instance when the tracking mechanism is engaged. (b) A histogram of the green light intensity. The deviation of the maximum position from 1 corresponds to the difference, , between the green light focus point and the tracking origin, and the width indicates the standard deviations , , and .

Image of FIG. 4.
FIG. 4.

(a) The 3D trajectory of a gold particle obtained by measuring the counter movement of the translation stage. For clarity, only every ten points are shown here. (b) The mean square displacement of the particle from the origin is ploted as a function of time. The solid line is a fit to a mixed diffusive and directional motion.
