ABSTRACT:
A light aperture apparatus (1) used with an auto imaging machine comprises an aperture mask (30), a transparent structure (20), and an circuit chip (10), wherein the aperture mask is constructed of an opaque material and has a plurality of holes formed therein. The further the hole is from a center of the aperture mask, the larger the diameter of the hole is. The transparent structure has a plurality of lenslets (26) on it. Each lenslet corresponds in position to a hole of the aperture mask. The circuit chip has a plurality of detector areas (14) surrounded by non-detector areas (15). Each detector area corresponds in position to a lenslet on the transparent structure.
