Figure 1

Schematic diagram showing the setup used for image-based feedback. Two immiscible phases (fluorous oil and water) are pumped into a microdevice featuring a flow-focussing section, by pressurised air controlled by bespoke feedback software. Image acquisition is synchronised to the presence of a droplet using the backscatter signal from a IR laser. The droplet length can be measured using simple image processing, the volume can be calculated and this information fed back to the control of the pump.
