Abstract
The use of an ultrasonic array system is described, which can be used combined with 3D reconstruction calculations. In this way ultrasonic reflection and backscatter from the inside of concrete members can be imaged and interpreted. The application of the system is demonstrated for two examples: Measuring the concrete cover of utility pipes in a tunnel and the examination of transversal ducts in a bridge plate.
