摘要
An apparatus for capturing an image of at least one object appearing in an imaging field of view (FOV). A housing has an imaging sensor operably coupled with the circuit board, the imaging sensor configured to capture an image frame appearing in the imaging FOV and defining an imaging axis. An illumination assembly has a plurality of light sources operably coupled with the circuit board, a diffuser positioned adjacent to the plurality of light sources, the diffuser configured to generate a diffused light pattern, and a light pipe positioned adjacent to the plurality of light sources to generate a direct illumination pattern and an off-axis illumination pattern, wherein the direct illumination pattern is oriented generally parallel to the imaging axis and the off-axis illumination pattern is configured to intersect the imaging axis.
