A1 - Schubert, Marcus T1 - Requirements for a Small Size Ultrasonic Imaging System for Inspection of Concrete Elements T2 - 19th World Conference on Non-Destructive Testing 2016 N2 - Ultrasonic imaging systems usually require an array of ultrasonic transducers for data acquisition on a wide area on top of an object under investigation. The goal of an imaging algorithm is the use of reflected ultrasound data to form a recognizable image. Conventional algorithms like SAFT are based on an inverse Huygens' principle and need therefore a dense measurement grid. This requires a big effort in data capturing. For simple and inexpensive measurement different strategies of imaging with reduced amount of data and examples with a manual scanning device on concrete elements are presented.
