Compound-eye imaging device

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.
