| 摘要 |
A color image reading apparatus comprises a plurality of line sensors which are a plurality of one-dimensional sensor arrays disposed on a single substrate, a projection optical system for projecting an image of a subject on the sensors, a blazed diffraction grating disposed in an optical path between the projection optical system and the sensors to separate light from the subject into a plurality of color lights, and a wavelength selection device disposed in an optical path between the subject and the sensors to permit only a beam of light within a specific wavelength range to pass therethrough.
