In this movie consecutive depth slices from a depth of 6 cm to 70 cm (slices parallel to the box girder wall) are shown. The reinforcement near the surface is not visualised. In a depth from 11 cm to 26 cm reflections of the tendons can be recognised. The stirrups are hardly visible in a depth from 30 cm to 37 cm. The reinforcement of the backside, (beginning in a depth of 47 cm), is partially visible, but only in the area, which is not affected by the shadows of the tendons. Reflections from the backside can be detected in a depth from 52 cm to 63 cm following the depth change of the box girder wall.
