ABSTRACT:
A scan line of an original document is divided into first and second halves, and first and second optical systems focus first and second images of the first and second halves onto a linear array of photosensitive elements such as photodiodes. The first and second images are each coextensive with the array and superimpose. A rotary shutter alternatingly blocks the first and second images so that only one of the first and second images is incident on the array at any time.
