A method and apparatus for determining a thickness of an object using ultrasonic signals are disclosed. The method includes the steps of transmitting ultrasonic signals toward the object, digitizing a reflected echo sequence of the ultrasonic signals, including interpolating the echo sequence, and processing the echo sequence by detecting maximum amplitude peaks in the echo sequence and determining the object thickness based on a time duration between the maximum amplitude peaks.

Ultrasonic measurement apparatus and method

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).

Method for the non-destructive testing of objects using ultrasound

A method and a device for testing a structural component having a complex surface contour utilizing ultrasound, at least one ultrasonic head (UPK) being guided along the surface contour (OK) of the structural component (BT) by means of a manipulator (MM) having several axial drives (MX, MJ, MZ, MA, MB) in several axes at a defined spacing (A) along the surface contour (OK) of the structural component (BT). To also ensure a high measuring accuracy in structural components which have a complex curved surface contour, the axial drives (MX, MJ, MZ, MA, MB) of the manipulator (MM) are synchronously moved along predetermined support points, a trigger drive (MRT) is controlled in synchronism with the axial drives (MX, MJ, MZ, MA, MB) and moved together with all engaged axial drives according to a predetermined surface line (OL) reproducing the surface contour (OK) and the trigger drive (MRT) generates equidistant trigger pulses relative to the surface line (OL) of the complex surface contour.
