More Information
Summary:Embodiments of the present disclosure include near co-axial polarized illuminator apparatuses and uses thereof. The near co-axial polarized illuminator is internally positionable in near co-axial alignment with one or more imager(s) utilized to capture a representation of a field of view illuminated by the near co-axial polarized illuminator. Embodiments include small form factor reader(s) that utilize a near co-axial polarized illuminator to improve illumination of a field of view captured via multiple imagers for detecting and/or decoding machine-readable symbologies, such as barcodes. Some embodiments include a DPM channel image sensor, a standard range channel image sensor, a near co-axial polarizer light source positioned adjacent to the DPM channel image sensor and adjacent to the standard range channel image sensor, a near co-axial polarizer aligned with the near co-axial polarizer light source, and an analyzer aligned with the DPM channel image sensor and/or the standard range channel image sensor.
