WebTwo echo signals are now recorded: one for the droplet at its initial known position and one for the droplet at its new unknown position after displacement. Subtracting the delays of the 2 echoes leads to an accurate determination of the unknown position provided that the droplet characteristics remain identical for the 2 considered positions.
