20160103081 | METHOD AND DEVICE FOR OPTICALLY INSPECTING FAULTS - In a method for optically checking a large-area three-dimensional object an illumination surface of parallel light beams is generated using a light source, a large-area three-dimensional object is partly or completely illuminated by the illumination surface, and a change of the parallel light beams of the illumination surface through the object is detected, wherein a projection surface is arranged on an object face opposite the light source, and the object shadow cast on the projection surface by the illumination surface is detected using an optical detection device. The strip-shaped light curtain is produced with a Fresnel lens. The shadow is detected using an optical lens system or a CCD camera. The dimensions of the object parallel to the projection surface are ascertained and compared with specified reference values. The projection surface is an opaque panel made of a translucent material or a surface-treated glass pane. | 04-14-2016 |
20130194102 | METHOD AND DEVICE FOR INDICATING AUTOMATICALLY IDENTIFIED FLAWS - A method is provided for indicating automatically identified flaws on or in a test specimen. A location of a defect on or in a test specimen identified by an inspection unit is subsequently indicated. A lighting unit, for example color LEDs, is used to generate an illuminated indicator marking the location of the defect on the surface or on at least one adjoining lateral edge of the test specimen. After the automatic identification of the flaw, it is checked on the basis of quantifiable properties of the defect whether the defect meets a predefinable quality criterion, and an illuminated indicator marking the location of the defect at or on the test specimen is generated only if the quality criterion is not met. The coloring of the marking illuminated indicator is predefined depending on quantifiable properties of the defect. | 08-01-2013 |
