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.

Abstract: An aiming system for use in a small height scan engine chassis. The aiming system includes a beam source assembly generating an input beam along a central axis and a collimator assembly having a lens group that defines a tilt axis having a tilt angle, α, relative to the central axis, to deflect the input beam from the central axis onto the tilt axis. The collimator assembly further includes a recess within which a diffractive optical element is sealably mounted to convert the deflected input beam into an aiming pattern at a focal distance of the lens group.

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 system and methods for providing aiming guidance for an imaging system. The system includes an illumination field source configured to provide illumination along a illumination optical axis to (i) illuminate a target and (ii) indicate a near field of view of the imaging system and a far field aiming source configured to provide a radiation pattern along an aiming optical axis to indicate a far field of view of the imaging system. Near field optics are configured to receive the first illumination from the near field illumination source and to form the first illumination to provide illumination to, and indicate to a user or machine vision system, the near field of view of the imaging system, and far field optics are configured to receive radiation from the aiming source and provide the radiation pattern to the far field to indicate the far field of view of the imaging system.

Abstract: An imaging engine including a telephoto lens for compact long range barcode readers is disclosed herein. An example imaging engine includes an imaging sensor and a telephoto lens assembly. The example telephoto lens assembly includes a first lens, disposed along an optical axis; a second lens, disposed along the optical axis to correct for pupil aberrations of the image projected after a fourth lens onto the imaging sensor; a third lens, disposed along the optical axis to correct for chromatic aberration of the image projected after the fourth lens onto the imaging sensor; and the fourth lens, disposed along the optical axis to correct for optical field curvature of the image projected after the fourth lens onto the imaging sensor.

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.
