Title:
METHOD FOR THE NON-DESTRUCTIVE TESTING OF A TEST OBJECT BY MEANS OF ULTRASOUND AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/009281
Kind Code:
A3
Abstract:
A method for the nondestructive testing of a test object by ultrasound, the method including generating a pulsed ultrasonic field in the test object by means of an array of individually drivable ultrasonic transmitting transducers acoustically coupled to the test object, by the ultrasonic transmitting transducers each being driven with a specific analog transient excitation signal, wherein each analog transient excitation signal is generated based on an ultrasonic transmitting transducer-specific stored digital transient excitation function, receiving resulting echo signals from the test object by means of an array of individually drivable ultrasonic receiving transducers, with each ultrasonic receiving transducer providing an analog time-resolved echo signal, temporarily storing the time-resolved, transducer-specific, digitized echo signals in the form of an echo signal set, and applying a plurality of different reception processing rules to the echo signal set.
