This paper presents test methods and preliminary results concerning determination of gas volume fraction in the aeration column with use of image tomography. In the presented method, image of the flowing gas bubbles is registered in two perpendicular directions of observation. The image is registered by one camera and a suitable system of mirrors. The proposed method allows to reconstruct bubble shapes and determine their trajectories in the aeration column.
