Point-of-transaction workstation for imaging indicia over full coverage scan zone occupied by asymmetrical light collection regions

摘要

A bi-optical, dual window, point-of-transaction workstation images indicia associated with multi-sided products over a full coverage scan zone by asymmetrically splitting the field of view of at least one imager into light collection regions of different spatial volumes. The light collection regions fill the scan zone and minimize dead areas therein. A smaller light collection region images one side of the product, while a larger light collection region images more than one side of the product. All sides of the product are imaged in the light collection regions. Twisting of the light collection regions relative to at least one of the windows is minimized so that the light collection regions fit fully with minimal clipping through each window. Illumination light is directed away from a user's eyes.
