METHOD FOR THE NON-DESTRUCTIVE TESTING OF OBJECTS USING ULTRASOUND |
摘要 |
<p>The invention relates to a method for processing signals which are generated by the reflection of ultrasonic waves by defects in the surface of objects during the non-destructive testing of objects such as pipes, bars, sheet metal, or uniform and complex carbon-fiber components. Said method comprises the following steps: emission of a complete wavefront onto at least one test section of the object, using a plurality of independent emission elements; receiving a wave reflected by the structure of the object by means of a plurality of receiver elements that are independent of one another; digitalization of the signals received by the receiver elements in digitizing steps; continuous modification of delay values and/or the number of receiver elements for each digitalization step (on-the-fly).</p> |
