Abstract:
1. A point-of-transaction workstation for electro-optically imaging indicia associated with multi-sided products, comprising: a housing; a window supported by the housing; a solid-state imager supported by the housing and having a two-dimensional array of sensors with a field of view; an optical system supported by the housing and operative for asymmetrically splitting the field of view of the imager into at least one light collection region in which return light from the indicia is captured by the imager through the window from one side of the product, and into at least another light collection region in which return light from the indicia is captured by the imager through the window from more than one side of the product, the other light collection region having a greater spatial volume than the one light collection region; a controller for controlling the imager and for processing the captured return light in at least one of the light collection regions; wherein the window is located in a generally horizontal plane; wherein the sensor array faces upwardly toward the generally horizontal plane; wherein the optical system includes an optical splitter above the imager for splitting the field of view into a pair of first subfields of view in a first split; and wherein the optical splitter has one reflecting surface above one half of the sensor array, and another reflecting surface above the other half of the sensor array; wherein the optical system includes two pairs of fold mirrors, each pair of fold mirrors being positioned in a respective first subfield of view for splitting the respective first subfield of view into a pair of second subfields of view in a second split; wherein the optical system includes two additional pairs of fold mirrors, each additional pair of fold mirrors being positioned in a respective second subfield of view for reflecting the respective second subfield of view as the asymmetrical light collection regions through the window; and wherein the optical system twice splits the field of view of the imager as a result of said first and second splits into two of the one light collection region of substantially equal smaller spatial volume and two of the other light collection region of substantially equal greater spatial volume; and wherein all four of the light collection regions pass through the same window along different intersecting directions.
