ABSTRACT:
An optical system for generating multiple linear images of an illuminated object line and focusing the image onto an image plane. The multiple images are generated on the object side of the lens using optical beam-splitting techniques. In a preferred embodiment, the images are converted into electrical signals after focusing onto photosensor arrays.
