Scanner with multiple resolution has mirror group, lens group with exactly one lens per light path, detector group with detector at each image position and optical output surface

摘要

The scanner has a mirror group (40) with at least one mirror for transferring light from the object along several separate light paths. There is a lens group (50) with several lenses for forming images of the object at several image positions, with exactly one lens per light path. A detector group (60) comprises several detectors, one at each image position, and at least one optical output surface (85). Each lens corresponds to exactly one detector, and the optical output surface is supplied with light that has passed through one lens and onto one detector at each resolution.
