Abstract

An optical reader for reading optical indicia which includes an imaging element for forming an image of the optical indicia at an image plane. The optical reader further includes an aperture positioned at the image plane and having a width smaller than the width of a smallest element in the image to be discerned by the optical reader, the aperture permitting illumination from a portion of the image to impinge upon a photodetector. The optical reader further includes a displacement system which produces relative movement between the image and the aperture to produce an output of the photodetector indicative of the optical indicia.
