Abstract:
1. A compound-eye imaging device comprising: an optical lens array with multiple integrated optical lenses; a stop member for shielding unnecessary ambient light from entering the optical lenses; a photodetector array placed at a predetermined distance from the optical lens array for imaging images formed by the optical lenses, respectively; and a light shielding block placed between the optical lens array and the photodetector array for partitioning a space between the optical lens array and the photodetector array into a matrix of spaces, with light-passing holes, as seen on a plane perpendicular to the optical axis of each optical lens so as to prevent lights emitted from the optical lenses from interfering each other, wherein the light shielding block is formed of a stack of multiple unit plates, each of which has multiple light-passing windows at horizontal positions thereon corresponding to horizontal positions of the optical lenses for passing lights emitted from the optical lenses so as to form the light-passing holes, respectively, and wherein each of the light-passing holes formed by the light-passing windows in the unit plates in the stack has an irregular inner wall surface serving as a light scattering surface.
