Barcode-reading system
First Claim
1. A barcode reader, comprising:
- a semiconductor package comprising a plurality of stacked silicon dies, wherein a first die positioned on top of the plurality of stacked silicon dies includes a two-dimensional array of photo sensors and image read-out circuitry, wherein the image read-out circuitry is coupled to the two-dimensional array of photo sensors and configured to generate a frame of image data, and wherein the frame of image data is a sequence of values, each value representing an intensity of illumination focused on one of the photo sensors; and
an optic system for focusing an image of a barcode on the two-dimensional array of photo sensors, the optic system including a lens assembly and a mirror, wherein the mirror folds an optical path behind the lens assembly onto the array of photo sensors, and wherein both the lens assembly and the mirror are positioned above the two-dimensional array of photo sensors.

Abstract
A barcode reader is disclosed. The barcode reader may include a semiconductor package and an optic system. The semiconductor package may include a plurality of silicon dies stacked vertically and interconnected by through-silicon vias (TSVs) or wires. A first die positioned on top of the plurality of stacked silicon dies includes a photo sensor array and image read-out circuitry. The image read-out circuitry is coupled to the photo sensor array and configured to generate a frame of image data, wherein the frame of image data is a sequence of values, each value representing an intensity of illumination focused on one of the photo sensors. The optic system is configured to focus an image of a barcode on the photo sensor array. The optic system includes a lens assembly and a mirror. The mirror folds an optical path behind the lens assembly onto the array of photo sensors.
