A method for decoding first and second optical codes from respective first and second objects passing at different locations through a view volume, the method comprising: capturing a first field of view through a housing window by a first region (163, 165) of an imager along a first image path, the first field of view defining a first volume within the view volume, the first field of view having a first bisecting plane, and the first field of view having a first depth of field within the view volume; capturing a second field of view through the housing window by a second region (163, 165) of the imager along a second image path, the second field of view defining a second volume within the view volume, the second field of view having a second bisecting plane, and the second field of view having a second depth of field within the view volume, wherein the first and second bisecting planes intersect each other at a nonzero angle of less than 10 degrees in the view volume, and wherein a first internal path length from the housing window to the imager along the first image path is longer than a second internal path length from the housing window to the imager along the second image path, thereby causing the second depth of field to extend more distally from the housing window into the view volume than the first depth of field extends from the housing window into the view volume; forming a first image at the first region (163,165); forming a second image at the second region (163,165), and determining the first optical code based on at least the first image from the first field of view and determining the second optical code based on at least the second image from the second field of view; characterized in that the first field of view is captured through the housing window by the first region (163, 165) of the imager via a first set of a plurality of first fold mirrors along the first image path; the second field of view is captured through the housing window by the second region (163, 165) of the imager via a second set of a plurality of second fold mirrors along the second image path; wherein the number of first fold mirrors is greater than the number of second fold mirrors; and wherein the first and second image paths propagate through a shared stationary lens to reach the first and second regions (163,165) of the imager. capturing a first field of view through a housing window by a first region (163, 165) of an imager along a first image path, the first field of view defining a first volume within the view volume, the first field of view having a first bisecting plane, and the first field of view having a first depth of field within the view volume; capturing a second field of view through the housing window by a second region (163, 165) of the imager along a second image path, the second field of view defining a second volume within the view volume, the second field of view having a second bisecting plane, and the second field of view having a second depth of field within the view volume, wherein the first and second bisecting planes intersect each other at a nonzero angle of less than 10 degrees in the view volume, and wherein a first internal path length from the housing window to the imager along the first image path is longer than a second internal path length from the housing window to the imager along the second image path, thereby causing the second depth of field to extend more distally from the housing window into the view volume than the first depth of field extends from the housing window into the view volume; forming a first image at the first region (163,165); forming a second image at the second region (163,165), and determining the first optical code based on at least the first image from the first field of view and determining the second optical code based on at least the second image from the second field of view; characterized in that the first field of view is captured through the housing window by the first region (163, 165) of the imager via a first set of a plurality of first fold mirrors along the first image path; the second field of view is captured through the housing window by the second region (163, 165) of the imager via a second set of a plurality of second fold mirrors along the second image path; wherein the number of first fold mirrors is greater than the number of second fold mirrors; and wherein the first and second image paths propagate through a shared stationary lens to reach the first and second regions (163,165) of the imager.
