Abstract: The invention relates to a method for combining a composite image (4) of an object (8) composed of multiple sub-images (6) by means of so-called stitching. Multiple adjacent sub-images (6) of the object (8) are captured and are stitched by means of an image processing operation together to form a coherent composite image (4). In order to make it possible to stitch the sub-images (6) together in the correct position even in the case of little information about the image, it is proposed that the stitching of the sub-images (6) together to form the composite image in the image processing operation be performed using an optical pattern (30, 74) that is generated by means of a pattern means (44).

Abstract: An arrangement for transporting a flat substrate through a coating installation, wherein the coating installation comprises, e.g., several and different sputter cathodes, to which the flat substrate, for example a glass pane, is transported one after the other in vacuo. So that no abrasion is generated between glass pane and contact, the glass pane is kept spaced apart from the contact by means of gas pressure. The gas pressure is herein built up through relatively few and small holes in a gas channel. Since during flooding of the coating installation to atmospheric pressure or during evacuation, due to the small holes, no fast pressure equalization between gas channel and the remaining coating installation is possible, the gas channel is decoupled in terms of gas from the remaining coating installation and provided with a separate gas line, via which gas can be introduced into the gas channel or pumped out of it.
