Bei einem Verfahren zur Prüfung von bruchgetrennten Bauteilen wird festgestellt, ob an wenigstens einer Bruchstelle ein geometrischer Versatz zwischen den Bruchflächen besteht. Erfindungsgemäß wird an wenigstens einer Bruchstelle in Bezug auf beiderseits der Bruchstelle angeordnete Flächen ein geometrischer Versatz der Flächen in Richtung der Flächennormalen optisch gemessen.

Die Erfindung betrifft eine Inspektionsvorrichtung (1) für Behältnisse (10) mit einer ersten Beleuchtungseinrichtung (4), welche wenigstens einen Anteil der Mantelfläche (10a) des Behältnisses (10) beleuchtet, einer Bildaufnahmeeinrichtung (8), welche das von der Beleuchtungseinrichtung (4) auf die Mantelfläche (10a) ausgestrahlte und von der Mantelfläche (10a) zurückgeworfene Licht wenigstens teilweise aufnimmt, wobei die erste Beleuchtungseinrichtung (4) in einer Längsrichtung (L) des Behältnisses wenigstens teilweise oberhalb des beleuchteten Anteils der Mantelfläche (10a) angeordnet ist. Erfindungsgemäß weist die Inspektionsvorrichtung (1) eine zweite Beleuchtungseinrichtung (6) auf, die einen Anteil der Mantelfläche (10a) beleuchtet, wobei die zweite Beobachtungseinrichtung in der Längsrichtung (L) des Behältnisses (10) wenigstens teilweise unterhalb des beleuchteten Anteils der Mantelfläche (10a) angeordnet ist.

Ein optisches Lochsuchgerät für in ihrer Längsrichtung vorgeschobene Bahnen (17) weist zwei im Abstand entlang der Bahn angeordnete Laserabtastgeräte (12, 15) auf, denen jeweils eine in Reflexion arbeitende Lichtempfangsanordnung (11, 14) zugeordnet ist. Die beiden Lichtempfangsanordungen (11, 14) sind an eine Auswerteelektronik (18) angeschlossen, in deren die beiden an gleichen Stellen der Bahn (17) erfaßten photo elektrischen Empfangssignale korreliert und daraufhin untersucht werden, ob sie gleich sind oder nicht.

Device for measuring surface properties of optical media stampers comprising a turntable for rotating the stamper, the measuring device comprising
at least one light source (1, 1') for emitting a light beam, which is directed onto a surface of the stamper (10), stray light detector means (9, 9') for detecting stray light, which is reflected from the stamper (10) surface under angles differing from the direct reflexion angle of the incident light beam.

A double-sided optical inspection system is presented which may detect and classify particles, pits and scratches on thin film disks or wafers in a single scan of the surface. In one embodiment, the invention uses a pair of orthogonally oriented laser beams, one in the radial and one in the circumferential direction on both surfaces of the wafer or thin film disk. The scattered light from radial and circumferential beams is separated via their polarization or by the use of a dichroic mirror together with two different laser wavelengths.

An apparatus for optically checking the exterior quality of bulbous or vegetable products of various shapes and sizes, comprises means (12) for conveying a succession of fruit or vegetable products (1) along a path from an entry (2) to an exit (3) of the apparatus and a first observation station (4) positioned along the path and provided with at least a primary camera (40) in such a way as to define a primary field of view (41) for the observation of a first segment (42) of the path. A second observation station (5) is positioned along the path downstream of the first observation station (4) and is provided with at least a secondary camera (50) in such a way as to define a secondary field of view (51) for the observation of a second segment (52) of the path separate from the first segment (42). Means for upsetting the fruit or vegetable products (1) are structured in such a way as to act exclusively in a third segment (62) of the path interposed between the first and the second segment (42, 52), therein upsetting every fruit or vegetable product (1) from a first position, in which a first surface portion (10) of the fruit or vegetable product (1) falls within the primary field of view (41) when the fruit or vegetable product (1) is in the first segment (42) of the path, to a second position, in which a second surface portion (11) of the fruit or vegetable product (1), at least complementary to the first surface portion (10), falls within the secondary field of view (51) when the fruit or vegetable product is in the second segment (52) of the path.
摘要:
The present invention relates to an article inspection apparatus. The apparatus includes conveying means (6) for conveying an article (5) through an inspection site (I) and rotating the article (5) aboutan axis (F). The article (5) is viewed by an imaging system including a first and a second image capture means (1A, 1B) and a mirror arrangement (7, 8) that defines the field of view of said first andsecond image capture means (1A, 1B). The imaging system is arranged so that the first image capturemeans (1A) has a field of view including a top view and a first upper side view of an article (5) on said conveying means (6) and the second image capture means (1B) has a field of view including a top viewand second upper side view of said article (5), wherein said second upper side view opposes said firstupper side view. Multiple lanes arranged side by side may be provided and lighting that provides substantially uniform light over the article (5) is also provided.
摘要:
The two sides of a flat panel are inspected in successive inspection stations each of which includes a camera having a linear array of CCD elements which generates an image line-by-line from a stripe of light reflected by one flat surface of the panel as the panel is conveyed through the inspection station. The signals representing images of the two faces of the panel are independently digitized and stored in separate pixel arrays of gray-scale values. The images are queued for filtering followed by processing by a single image processing board which generates a table of hits, identified as pixels having gray-scale values which breach preselected thresholds. Sections of the stored pixel array are transmitted sequentially to the image processing board which has a frame size smaller than the stored array, with the frame sized sections overlapping as required to confine the pixels processed to those inside the edges of the panel image. A microprocessor analyzes the hits identified by the image processing board and generates a reject signal if the density of hits exceeds a limit. The microprocessor also associates hits by proximity into blobs and rejects the panel if a weighted count of hits in any blob exceeds predetermined criteria.
