Abstract

In the case of a plate-shaped substrate material (20), in which a microfluidic structure (5) is formed, there is consequently the ability for light (11, 12) that was diffusely scattered by an inner wall (9) to be captured and that a fill level, a speed of advance or any other variable for characterizing a liquid transport of a liquid (8) in the microfluidic structure (5) be ascertained by calculation from the captured, diffusely scattered light (11, 12).
