Abstract:
1. A point-of-transaction workstation for processing products by electro-optically imaging indicia associated with the products, comprising: a housing; at least two substantially orthogonal window one window supported by the housing; at least two solid state imagers supported by the housing and each of the two solid state imagers are operative to capture return light from the indicia through a corresponding one of said solid state imager over a field of view, the at least two imagers each having an array of sensors arranged along mutually perpendicular row and column array axes to each other; an optical system supported by the housing and operative for directing the captured return light along an optical path from each of the at least two windows to each corresponding solid state imager, and for splitting the field of view of the at least two solid state imagers into a plurality of corresponding subfields of view, the optical system having a plurality of fold mirrors each positioned in the optical path to fold the captured return light in at least one of the subfields of view about a respective rotating axis, wherein the respective rotating axis of each given fold mirror selected from the plurality of fold mirrors in the optical path is substantially parallel to a projected array direction defined as one of the row or column array axes in the at least one imager projected backward onto said given fold mirror through all intervening fold mirrors in the optical path between said given fold mirror and the at least one imager, wherein the positioning of the fold mirrors is chosen to result in a resistance of skewing of the at least one subfield of view relative to each of the at least two windows; and a controller for controlling the at least two imagers and operable to process the captured return light in the at least one subfield of view and to decode the indicia.
