What is it about?
In this study, we present an experimental method to measure the position in 3D space and size of air bubbles in a cylinder filled with water using a single cutting edge camera.

Why is it important?
Bubbly flows are encountered in many industrial and natural phenomena. The movement of bubbles in a liquid is mostly 3D and is hard to measure experimentally. Usually, 3D measurement requires at least two cameras, but we managed to do it using only a single camera.
Perspectives
These results will help to validate numerical simulation of bubbly flows. The next step will be to perform 3D velocity measurement of the bubbles.
