Claim:
1. An optical code reading system for forming image data from an item bearing an optical code present in a read volume, the system comprising: an imager; a dichroic mirror; a first optical path for a first field of view of the item from a first direction directed onto a first side of the dichroic mirror; a second optical path for a second field of view of the item from a second direction directed onto a second side of the dichroic mirror opposite the first side, wherein the dichroic mirror is operative to (a) transmit therethrough light of a first wavelength range from the first field of view of the item toward the imager and (b) reflect light of a second wavelength range from the second field of view of the item toward the imager; a focusing system for focusing the light of both the first wavelength range and the second wavelength range onto a common active area of the imager, wherein the imager acquires a 2D image of the first field of view and a 2D image of the second field of view; a first light source generating first illumination light in the first wavelength range for illuminating the item from a first direction; a second light source generating second illumination light in the second wavelength range for illuminating the item from a second direction, wherein the first and second light sources are controlled to illuminate in an alternating fashion.
