An optical imaging system (12) is to be aligned with its optical axis (16) in relation to a given alignment axis (14). For this, a radiation beam (30) is emitted from one side of the imaging system (12) along the alignment axis (14). In the direction of beam propagation, there is located behind the imaging system (12) a pair of diaphragm elements (24, 26), whose apertures are each covered by a piece of material transparent to the radiation, carrying a plurality of sensor elements arranged in a matrix. The sensor elements furnish information about the measured radiation intensity to a signal processing unit (42), which can graphically illustrate the current alignment status of the imaging system (12) on a monitor (44) and/or produce an automatic adjustment of the imaging system (12). |
