- Abstract:
- The paper presents an idea of a new measuring method based on image tomography. This method insists in registration of images of the moving bubbles from two perpendicular directions. Two images are used for determination of the center of mass, movement trajectory and local velocities. Volume and area of the bubble are defined by approximation of the bubble shapes by the known geometric figures. The paper also presents the algorithm of reconstruction of the bubble shapes and movement trajectories, as well as exemplary test results. The obtained results were compared with theoretical relationships published in literature.
