Method using ultrasound for the non-destructive examination of a test body

摘要

The invention is a method using ultrasound for non-destructive examination of a test body, whereby ultrasonic waves are coupled into the test body with one ultrasonic transducer or a multiplicity of ultrasonic transducers and the ultrasonic waves reflected inside the test body are received by a multiplicity of ultrasonic transducers and converted into ultrasonic signals. The ultrasonic signals detected in the single measurement periods are individually stored and are accessible for off-line evaluation after termination of the measurements. Application of corresponding reconstruction algorithms permits subsequent synthetization of any desired ultrasonic coupling-in angles and focussing into the volume region of the test body from the stored ultrasonic signals without requiring any additional ultrasonic measurements.
