Barcode reader having multiple illumination systems and multiple sets of imaging optics
First Claim
1. A barcode reader, comprising:
- a first lens assembly with a first field of view and a first optical path for receiving first illumination from the first field of view to project an image of the first field of view onto a first image sensor section;
a second lens assembly with a second field of view and a second optical path for receiving second illumination from the second field of view to project an image of the second field of view onto a second image sensor section;
a first illumination system outside of the first field of view projecting the first illumination into the first field of view at a point spaced from the first lens assembly in the direction of the first field of view; and
a second illumination system positioned between the first lens assembly and the point from which the first illumination system projects the first illumination into the first field of view, the second illumination system being outside of the second field of view and projecting the second illumination into the second field.

Abstract
A barcode reader comprises a first lens assembly with a first field of view and a first optical path for first illumination from the first field of view to project to a first image sensor section. The barcode reader further comprises a second lens assembly with a second field of view and a second optical path for second illumination from the second field of view to project to a second image sensor section. The barcode reader further comprises a first illumination system positioned outside of the first field of view projecting the first illumination into the first field of view at a first angle from the first optical path. The barcode reader further comprises a second illumination system positioned between the second lens assembly and a point from which the first illumination system projects the first illumination into the first field of view.

11. A barcode reader, comprising:
-
an image sensor configured to capture an image of a barcode within a field of view of the barcode reader; an imaging system with an optical path from the image sensor to the barcode and providing at least two corresponding images of the barcode on the image sensor; a first illumination system positioned outside of the field of view projecting first illumination into the field of view at a first angle from the optical path; and a second illumination system positioned between the imaging system and a point from which the first illumination system projects the first illumination into the field of view, the second illumination system being outside of the field of view and projecting second illumination into the field of view at a second angle from the optical path, the second angle being different than the first angle. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A barcode reader, comprising:
-
an image sensor configured to capture an image of a barcode within a field of view of the barcode reader; an imaging system with an optical path from the image sensor to the barcode and providing an image of the barcode on the image sensor; a first illumination system positioned outside of the field of view projecting illumination with a first illumination spectrum into the field of view at a first angle from an optical path from the image sensor to the barcode; and a second illumination system positioned outside of the field of view projecting illumination with a second illumination spectrum into the field of view at a second angle from the optical path, the second angle being different than the first angle and the second illumination spectrum being broader than the first illumination spectrum. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
