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.
Claims13
A multiple-resolution scanner for scanning a scanned object at one of several resolutions, comprising:
- a scanning device, further comprising
- a mirror group having several mirrors for transmitting light from said scanned object along several light paths that are separate from each other,
- a lens group having several lenses, one of said lenses placed in each of said light paths, for generating images of said scanned object at several image positions, and
- a detector group having several detectors, one of said detectors placed at each of said images positions, said detectors generating electrical signals;
- and
- a switching device, passing said electrical signals of at least one of said detectors to a signal processing unit for further processing and switching between said electrical signals of said detectors electronically.
