In the described optical device a linear object element forms an image by two straight lines crossing each other at a specific angle. Thus it is possible to achieve a crosswise movement of the image point downstream of the optical device with only a single linear scanning movement upstream of the optical device. In particular it is possible to scan plane structures with a single scanning movement.

Optical device for forming an image in the form of crossed linear image elements from an object consisting of first and second linear object elements which are arranged substantially parallel to each other, said optical device comprising: (a) a first beam deflecting means for rotating a beam path for the first object element; and (b) a beam superposing means arranged in a beam path of the first and second object elements downstream of the first beam deflecting means for directing the two beam paths to a common image area to form crossed linear image elements.
