摘要:
A method and apparatus are disclosed for providing image data for generating an image of a region of a target object. The method includes the steps of providing incident radiation, focusing the radiation downstream or upstream of a target object and via at least one detector located downstream of a focusing element, detecting an intensity of radiation scattered by the target object at an observation plane offset from a back focal plane associated with the focusing element.

An apparatus and method of measuring an object (having at least two edges) projects a plurality of x-ray images of the object. At least two of the plurality of x-ray images are projected from different directions relative to the object. The apparatus and method also locate the at least two edges in the x-ray images, and ray trace a plurality of lines. Each ray traced line is tangent to at least one point on at least one of the located edges. Next, the apparatus and method reconstruct at least a partial wireframe model of the object from the tangent points of the ray traced lines. The wireframe model includes the at least two edges. Finally, the apparatus and method measure between the at least two edges of the at least partial wireframe model.

Die vorliegende Erfindung betrifft ein Verfahren zur Qualitätskontrolle von Bauteilen, die einer Wärmebehandlung unterzogen werden, wobei die Bauteile ein Gefüge aufweisen, welches mindestens eine Phase umfasst, die in mindestens zwei unterschiedlichen Formen im Gefüge der Bauteile vorliegt, und wobei mindestens ein Bauteil oder eine in Bezug auf das Material identische Probe einem Wärmebehandlungsschritt unterzogen werden, bei dem das Bauteil oder die Probe bei einer Temperatur ausgelagert werden, bei der die Phase in einer einzigen Form im Gefüge vorliegt und wobei der Gefügezustand bei der Wärmebehandlungstemperatur durch Abschrecken des Bauteils oder der Probe von der Temperatur des Wärmebehandlungsschritts eingefroren wird, und wobei die Probe oder das Bauteil in diesem Zustand nach dem Abschrecken einer Untersuchung mittels Röntgenbeugung unterzogen werden, um qualitativ und/oder quantitativ die Phase zu identifizieren.
摘要:
The invention relates to a device for testing the material of test objects (15) by means of X-ray radiation, comprising an X-ray device (20) which comprises an X-ray source (12) for irradiating a test object (15) maintained in a test position and an X-ray detector (13) designed as a line detector, and an electronic control element (38) which is designed to control the X-ray device (20). During X-ray testing, the test object (15) and the X-ray device can be rotated in relation to each other only about an essentially vertical rotational axis (R). The claimed device is characterised in that the X-ray detector (13) comprises at least two detection sections (13A, 13B,...) which are designed to detect the test object over a complete radial cross-section (52A, 52B,...).
摘要:
An X-ray inspection apparatus (10) is equipped with an X-ray irradiator (13), an X-ray line sensor (14), an image generating component (21a), a region identifying component (21b), a weight estimating component (2 1 c) and a weight determining component (2 1 d) and inspects a chain of connected packages (M) including a plurality of bags (N1, N2, ..., N6) that are connected in a chain. The X-ray irradiator (13) irradiates the chain of connected packages (M) with X-rays. The X-ray line sensor (14) receives the X-rays from the X-ray irradiator (13). The image generating component (21a) generates an X-ray image (P) on the basis of the X-rays that the X-ray line sensor (14) has received. The region identifying component (21b) identifies discrete package regions (C1, C2, ..., C6) from the X-ray image (P). The weight estimating component (21c) estimates weight values with respect to the discrete package regions (C1, C2, ..., C6). The weight determining component (21d) determines the chain of connected packages (M) as being abnormal in weight when any of the weight values falls outside a predetermined range.
摘要:
An X-ray inspection device (10) comprises a conveyor (50), an identification part (12B), a determining part (12C), and an operation controller (121). The X-ray inspection device irradiates articles with X-rays while the articles are being conveyed, and the articles are inspected. The conveyor (50) conveys the articles. The identification part (12B) identifies whether the articles are a test piece or a product. The operation controller (121) sets operation to a normal mode in which the article is determined to be defective or not defective in a case in which the article has been identified as an end product by the identification part (12B), and to a test mode in which the state of the device is assessed in a case in which the article has been identified as a test piece by the identification part (12B). As a result, the state of the X-ray inspection device can be assessed without halting production of the products.
