Abstract:
A method for the locally resolved measurement of a radiation distribution (24) produced using a lithography mask (16) comprises providing a radiation converter (31, 131) having an at least two-dimensional arrangement of converter elements (32, 132) which can respectively be put in an active and a passive state, and are configured to convert incoming radiation in respect of its wavelength in the active state. The method further comprises: manipulating the radiation converter (31, 131) several times such that respectively only a fraction of the converter elements (32, 132) adopts the active state, irradiating the radiation converter (31, 131) with the radiation distribution (24) after every manipulation of the radiation converter (31, 131) so that the active converter elements (32, 132) emit wavelength- converted measuring radiation (34), recording respective places of origin (54) of the measuring radiation at every irradiation with the radiation distribution (24). Moreover, the radiation distribution (24) produced by the lithography mask (16) is determined from the places of origin (54) recorded with the different irradiation steps.

Abstract:
A detecting system for detecting flaws in a sample (310) comprises an illumination assembly (320, 322) and detecting assembly (350, 354). The illumination assembly has an infra-red light source (320) and illumination optics (322) for directing a beam of light from the light source to a spot (346) on or within a sample. The detection assembly has a detector (354) for detecting light from an illuminated spot on or within a sample and detection optics (350) for directing light from an illuminated spot on or within a sample to the detector (354). Such a system may be used for determining flaws in a sample such as a thermal barrier coating on a turbine blade, or a dental or other medical part. In particular the system may be used for determining, flaws in a ceramic sample. A method for detecting flaws in a sample is further described.
Abstract:
A system and method for measuring the physical characteristics of a component where the system includes a light source, a sensing device, a reflecting device, and a retention mount. The method includes associating a component with the system such that the component is positioned within the retention mount and operating the system to cause the light source to emit a collimated light beam along a source optical path, where the collimated light beam is reflected to cause a reflected collimated light beam to propagate along a sensor optical path to be incident upon the component to produce a component silhouette where the sensing device generates data responsive to the silhouette. The image data is processed to generate resultant data responsive to the component, wherein the resultant data is further responsive to at least one of a smoothing algorithm, a functional size algorithm and a centering algorithm.
Abstract:
For computerized inspection for the determination of possible deviations in shape and size of objects (2) as compared to a reference, a scanner (8) with a digital camera (17) taking 2D-photos and a laser triangulation unit (16, 17) giving 3D-scannings are used, and the scanner (8) and the object (2) are moved in relation to each other during the scanning in order to change the position and/or orientation of the object (2) in relation to the scanner (8). A computer (11) is connected to the scanner, in which computer the reference, a predefined virtual object, e.g. from a CAD-drawing, is stored. The computer (11) has a software adapted on basis of the 2D-photo to determine the outlines of the object (2) in the scanned portion and on basis of the 3D-scanning to generate a three-dimensional photo of the surface within the portion. The computer (11) also has a software for the comparison of the scanned outlines of the object (2) and the three- dimensional surface within the portion with outlines and three-dimensional surface within a corresponding portion of the reference. The computer (11) is programmed to accept or reject the scanned object (2) depending whether possibly determined deviations fall within or outside the predefined tolerance limits.
