Abstract: An imaging lens assembly for an imaging reader includes a base lens having an optical power, a target side facing a target, and an imager side facing an imager. An aperture stop directly contacts the imager side and has an aperture through which return light from the target passes. The aperture is magnified in apparent size by the optical power of the base lens to form a magnified entrance pupil as seen through the target side. A variable focus liquid lens focuses the return light captured by the magnified entrance pupil over an extended range of working distances onto the imager. The magnified entrance pupil captures more of the return light from the target to pass through the base lens and the liquid lens to the imager, and also allows the target to be illuminated with a lower brightness to conserve electrical power.

Abstract: An imaging scanner includes an illumination light source and a hybrid illumination lens. The hybrid illumination lens includes a first Fresnel surface facing the illumination light source and a second surface having a microlens array thereon. The first Fresnel surface is configured to direct light received from the illumination light source towards the second surface to generate illumination light towards a target object through the microlens array on the second surface.

Abstract: An imaging scanner includes an aiming light source configured to emit visible light through both the shape defining element and the aiming lens arrangement to generate an aiming pattern on a target object. The shape of the aiming pattern changes with the distance between the target object and the imaging scanner. For determining the distance, the shape of the aiming pattern in a pixel data is compared with the expected shape of aiming patterns at multiple distances.

Abstract: Targets to be read by image capture are illuminated and imaged over an extended range of working distances. A near imager captures return light over a relatively wide imaging field of view from a target located in a close-in region of the range. A far imager captures return light over a relatively narrow imaging field of view from a target located in a far-out region of the range. A single illuminating light assembly is shared by both the near and far imagers. An illumination light source emits illumination light, and an illuminating lens assembly optically modifies the emitted illumination light, and simultaneously illuminates a wide illumination field to illuminate the target located in the close-in region of the range, and a narrow illumination field to illuminate the target located in the far-out region of the range.

Abstract: Indicia are imaged at a workstation having windows arranged in intersecting planes. The workstation also has solid-state imagers with fields of view that are split into intersecting subfields that look out through the windows, as well as illumination assemblies each having multiple light sources that illuminate each subfield with illumination light over an illumination field that overlaps a respective subfield. Light-modifying elements, such as lenses or baffles that are radially offset from the multiple light sources, condition the illumination light from the multiple light sources to be generally uniform in light intensity over at least one illuminated subfield.
