| 20120019651 | INSTALLATION OF 3D INSPECTION OF ELECTRONIC CIRCUITS - An installation of optical inspection of integrated circuits or the like, comprising: a photographic system placed above a scene in a plane defined by a first and a second direction, the photographic system comprising several digital cameras each comprising an orthogonal array of pixels, all cameras having their respective optical axes inclined by a first angle with respect to a third direction perpendicular to the two others; and two projectors of determined patterns, these patterns being such that two straight lines projected by each of the projectors are aligned in the plane defined by the first two directions and are coplanar with a straight line interconnecting the optical centers of the two projectors. | 01-26-2012 |
| 20120019650 | INSTALLATION OF OPTICAL INSPECTION OF ELECTRONIC CIRCUITS - An installation of optical inspection of integrated circuits or the like, comprising: a planar conveyor along a first direction of the objects to be analyzed and a photographic system placed above an area of the conveyor and in a fixed position with respect thereto, the photographic system comprising at least one first set of digital cameras each comprising an orthogonal array of pixels, said cameras being aligned in a second direction different from the first one, the cameras being all oriented so that one of the orthogonal directions of their pixel array forms a first angle with the first direction. | 01-26-2012 |
| 20110013009 | REFLECTION MICROSCOPE FOCUSING - The invention relates to a method of focusing, by an imaging device, of images of a substantially planar surface of an object including the step of determining the attitude of the surface of the object with respect to a reference plane by scanning this surface by means of at least one triangulation sensor along exactly two parallel lines in the reference plane. The invention further includes the steps of splitting the surface of the object into areas of a size corresponding to the size of a taken image, inferring from the attitude respective elevations of the image areas, and adjusting, for each area, the focus with respect to the elevation thereof. | 01-20-2011 |
