Abstract
A semiconductor detector device for detecting optical code symbols includes no more than 512 pixels. Each of the pixels has an aspect ratio that is greater than 2 to 1 with a short dimension not greater than 8 microns. In a bar code reader, a sensor for detecting the field of view of the reader includes a single semiconductor device having a collection of surfaces configured as a set of no less than 256 and no more than 512 pixels. Each of the pixels has an aspect ratio that is greater than 2 to 1, with a short dimension not less than 2 microns and not greater than 8 microns.
