A method for non-destructive examination of parts includes producing a 3-D image of a sample of a part, extracting a point cloud of the image of the sample of the part, and registering the point cloud to a CAD coordinate system. The second transport roller is mounted so as to be pivotable about a pivot axis disposed perpendicularly to its axis of rotation, preferably by a ball and socket joint or a fork bearing. The BMC generates an update signal according to on a reception state of the update instruction. A drain line bypasses the dispensing valve and features a check valve so that LNG trapped in the hose after dispensing is returned to the sump due to pressurization by ambient heat. The output signal or input signal is output or input via this floating isolation circuit. The phase mask is configured, in zones in which the distances between neighboring regions in at least one geometrical direction are less than a predetermined limiting distance, in each case as an alternating phase mask.
