| 1. A compound-eye imaging device comprising:
an optical lens array with multiple integrated 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 as seen on a plane perpendicular to the optical
axis of each optical lens to prevent lights emitted from the optical lenses from interfering each other,
wherein the light shielding block is formed of multiple flat unit plates which are stacked in direct contact with each other
between the optical lens array and the photodetector array and which have windows to form tubular apertures to pass lights
emitted from the optical lenses.
