ABSTRACT:
A multiple-resolution scanner for scanning a scanned object at one of several resolutions, comprising: a scanning device, having a mirror group, a lens group, and a detector group; and a switching device. The mirror group has several mirrors for transmitting light from the scanned object along several light paths that are separate from each other. The lens group has several lenses, which are separately placed in each of the light paths and generate images of the scanned object at the positions of several detectors of the detector group. The number of the light paths, lenses and detectors is the same. The detectors generate electrical signals, which are fed into the switching device for further processing and switching between the electrical signals of the detectors electronically.
