ABSTRACT:
The invention relates to an optical device that includes (a) a first optical element with at least one first raster element, where the first raster element has a first axis, (b) a second optical element with at least one second raster element, where the second raster element has a second axis. The first raster element can be changed in its position relative to the second raster element, so that a distance between the first axis and the second axis is variable.
