摘要
The invention relates to a device (68) and a method for the non-destructive testing of planar objects (70) such as thick or thin metal sheets using ultrasound in different focal zones, said device comprising one or more independently controllable probes (PK1 - PKn), and to the use of matrix phased array probes. To achieve uniform sensitivity over a wide thickness range, the probes (PK1 - PKn) are designed as 2-dimensional phased array probes (PK2 - PKn) and are located in rows offset in relation to one another. The sum of the number and length of the individual probes (PK1, PKn) corresponds to the width of the material to be tested.
