Abstract
A elliptical cylinder mirror system for use in a raster input scanning system which allows for high efficiency light gathering and reflection to a photosensitive device. Elliptical cylinder mirrors 10, 12 are placed adjacent to a scan line 14 on a document or other medium 8 to be scanned. The input light 38 is caused to raster scan the medium wherein the light reflected from the medium is now modulated by the information on the medium 8. One elliptical cylinder mirror 10 collects and focusses the reflected light from one side of the scan line directly onto a photosensitive or similar type of device 18. Another elliptical cylinder mirror 12 collects and reflects the light from the other side of the scan line towards a fold mirror 20 which, in turn, reflects the light toward the same or closely situated photodetector 18. A large proportion of the light reflected by the medium 8 is gathered by the mirrors 10, 12 for use in the photodetection process.
