Abstract: A technique is provided for determining an orientation of a defect present within a mechanical component using at least one ultrasonic head that applies ultrasonic signals to the mechanical component starting from various measurement points. Echo ultrasonic signals reflected by a point to be analyzed present within the component back to the measurement points are received by the same or a different ultrasonic head. A data processing unit analyzes the received echo ultrasonic signals as a function of a sound emission direction between each measurement ping and the point to be analyzed for determining the orientation of the defect. A distance between the measurement point and the point to be analyzed is calculated for every measurement point as a function of a signal propagation time between the point in time of emitting the ultrasonic signal and the point in time of receiving the echo ultrasonic signal reflected by a defect.

Abstract: A method and a device produce X-ray images of objects, according to which artifacts caused by scattered radiation are corrected. To this end, a modulator field is used, that can be moved from a first position to a second position, thereby enabling modulator field areas with small and relatively large X-ray attenuation coefficients to be interchanged. An initial amplitude-modulated projection of the object is respectively produced in each of the two positions, and a scattered image associated with the projection is respectively calculated. This is especially suitable for rapid CT scans.

Abstract: Automated inspection system and method are provided for nondestructive inspection and evaluation of an electrically-conductive workpiece based on induction thermography. A movable carriage (15) may be arranged to translate the workpiece in an inspection location (18). An induction coil 20 is disposed at the inspection location. The induction coil is responsive to an excitation current to induce a flow of electrical current in a region of interest of the workpiece. A thermographic camera (22) is disposed at the inspection location. The thermographic camera is arranged to capture data indicative of a thermal response resulting from the flow of electrical current. A computer system (30) is configured to process the data from the thermographic camera to generate an indication of a presence of a discontinuity (e.g., a subsurface crack) in the workpiece.

Abstract: A hand-held thermography system (8). A generator (10) supplies current to a transformer (15) in a handle (16). An induction coil (20) connected to the transformer (15) extends from the handle (16). The induction coil (20) induces eddy currents in a test object (50), producing a thermal topography on a surface (52) of the object (50) that reveals structural features including defects in the object. An infrared camera (24) mounted on the transformer (16) digitizes images of the thermal topography. A controller (12) processes the images, displays them on a monitor (14), and stores them in a digital memory (11) for evaluation. Digitized positional data relating the position of the image to the surface may also be stored. An operator (40) presses a trigger (17), signaling the controller (12) to start current to the induction coil (20) and simultaneously to acquire and process one or more images from the camera (24). The images may be evaluated visually and/or by computerized analysis techniques for analyzing defects in the object.
