Figure 13
Plane-wave pulse inversion images of a room-temperature water bath containing OFP droplets before (a) the droplet activation sequence and immediately after (b) the final pulse of the activation sequence. The focus of each preprogrammed activation pulse was shifted using electronic steering to create the desired pattern in a left-to-right, bottom-to-top order.
