摘要:
There is disclosed a light guide for guiding light from a light source in a longitudinal direction and radiating the light to illuminate an object to be illuminated, which includes a diffuser for diffusing the light from the light source along the longitudinal direction of the light guide, and a radiator for radiating the light diffused by the diffuser in a predetermined direction. By arranging the diffuser and the radiator so that a normal line passing through the center of the width of the diffuser is different from the predetermined direction at least in the vicinity of the light source when viewed in the longitudinal direction of the light guide, the illuminance distribution of the longitudinal direction of the light guide is uniformed.

In an image sensor having a photoelectric conversion element for receiving light, an illumination unit, and a lens array in which a plurality of gradient index lens elements for focusing light reflected by an original onto the photoelectric conversion element are arrayed, part of the peripheral portion of the lens of the gradient index lens element in the radius direction contains a light absorber for absorbing light having a predetermined wavelength other than the wavelength distribution of light emitted by the illumination unit. With this arrangement, since the optical influences of the peripheral portion of the lens element, which degrade the lens resolution can be eliminated, and the lens elements can be accurately arrayed, there can be provided an image sensor which is free from crosstalk between the lens elements although the lens elements are arrayed in tight contact with each other, and has a large focal depth by changing the angular aperture, high performance, and hardly any performance variations in mass production, and an information processing system using the image sensor.
