Abstract
A color image reading apparatus includes a plurality of line sensors formed by arranging a plurality of one-dimensional sensor arrays on a single substrate, a focusing optical system for focusing an object on the sensors, and a volume hologram, arranged in the optical path between the focusing optical system and the sensors, for color-separating light from the object into a plurality of color components and guiding the plurality of color components to the corresponding one-dimensional sensor arrays.
