Abstract
Vertical parallax between an imaging linear field of view (FOV) and an aiming light pattern is reduced in a reader for electro-optically reading symbols to be read by image capture by an arrangement that includes an imaging assembly having a solid-state imager with a linear array of image sensors, and an imaging lens for capturing return light over the imaging linear FOV from a symbol and for projecting the captured return light onto the linear array, an aiming light assembly spaced vertically away from the imaging assembly for generating the aiming light pattern on the symbol prior to reading, and an optical assembly for intercepting the aiming light pattern and for vertically aligning the aiming light pattern with the imaging linear FOV to reduce the vertical parallax.
