Abstract: An optical assembly for an autofocus lens system for imaging an object appearing in an imaging field of view (FOV) is provided. The optical assembly includes a compensator lens assembly disposed along an optical axis, with the compensator lens assembly configured to receive light along the optical axis and to provide tuning of a flange focal length of the optical assembly. A variable focus assembly, including a variable focus optical element, is disposed along the optical axis to receive light from the compensator lens assembly. The variable focus optical element has a tunable focal plane. A fixed focus optical group is disposed along the optical axis to receive light from the variable focus assembly, the fixed focus optical group is configured to focus the light at the flange focal length of the optical assembly.

Abstract: Methods and apparatus for locating small indicia in large images are disclosed herein. An example method includes: identifying an aiming pattern zone that includes a detected or presumed location of an aiming light pattern, wherein an offset between the location and a center of image data varies due to a parallax; determining one or more coordinates of the aiming pattern zone; capturing image data representing an image of an environment appearing within a field of view (FOV) of a scanner including the indicia; encoding the one or more coordinates into a tagline of the image; and providing the image with the tagline to an indicia decoder such that the indicia decoder attempts to decode the indicia from the image data starting in a region of the image data selected based upon the one or more coordinates.

Abstract: At least some embodiments of the present invention are directed toward optical arrangements for use in providing illumination light emitted by a barcode reader. In some embodiments, the arrangement includes an illumination source, a lens positioned within the path of the illumination light emitted by the illumination source where the lens is operable to collimate the light and redirect its central axis, and a window positioned within the path of the redirected and collimated light where the window is operable to alter the illumination light such that the resulting illumination light beam has a height-to-width ratio of less than 8 to 25.

Abstract: A scan engine for capturing at least one image of an object appearing in an imaging field of view (FOV) is provided that includes an imaging system, illumination system, aiming system, and a first and second chassis. The imaging system includes a lens holder and at least one lens disposed within the lens holder and both a far imaging system and a near imaging system for capturing images across multiple fields of view at different distances. The illumination system and aiming system are physically positioned to provide illumination of a target in the near and/or far fields of view, and provide an aiming pattern to the near and/or far fields of view.

Abstract: A scan engine for capturing images of an object appearing in an imaging field of view (FOV) includes a chassis including a chassis body defining at least one confined volume, an adhesive material, and an aiming system that generates a cosmetic pattern to assist with identifying the FOV. The chassis body includes a chassis mounting portion and a redirecting region that at least partially surrounds the chassis mounting portion. The adhesive material is disposable on the chassis mounting portion. The aiming system is at least partially disposed within the at least one cavity of the body and extends along a longitudinal axis in a first direction. At least a portion of the aiming system engages the adhesive material to be at least partially retained within the at least one confined volume of the body. Upon directing electromagnetic radiation towards the at least one confined volume, the redirecting region redirects the electromagnetic radiation towards the adhesive material to initiate a curing process.

Abstract: Methods and apparatus for aligning a lens holder in a small-height scan engine are disclosed herein. An example method for aligning a lens holder in a small-height scan engine includes: mounting an image sensor to a circuit board; optically aligning, using one or more alignment fixtures, a lens holder holding one or more lenses or optical elements with the image sensor based upon one or more images captured by the image sensor through the lens holder; and after the lens holder and image sensor are optically aligned, physically aligning, using the one or more alignment fixtures, the lens holder with the circuit board based upon a misalignment between a surface of the lens holder and an edge of the circuit board.

Abstract: Imaging arrangements and barcode readers including such imaging arrangements. An imaging arrangement for use in a barcode reader includes a housing. The imaging arrangement also includes a light source configured to emit light along a central light axis. The light source is disposed in the housing. The imaging arrangement also includes a lens having a first surface and a second surface opposite the first surface. The lens is disposed in the housing. The first surface is configured to face the light source and is structured to substantially collimate light received from the light source into a collimated beam. The second surface includes surface structures structured to generate a patterned beam in response to receiving the collimated beam.

Abstract: Embodiments of the present invention generally relate to the field of barcode readers, and more particularly, to barcode readers designed to operate in an environment with densely packed barcodes. In an embodiment, the present invention is a barcode reader that includes an imaging assembly operable to capture image frames; an aiming light assembly operable to emit an aiming light; and a controller configured to: decode a barcode within a decode frame image captured by the imaging assembly; upon decoding the barcode within the decode frame image, cause a capture of a picklist frame image; and report the barcode to an external host upon at least some overlap between a location of the barcode within the decode frame image and the location of the at least a portion of the aiming light pattern in the picklist frame image.
