Abstract: 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: Methods and systems to implement a miniature long range imaging engine with auto-focus, auto-zoom, and auto-illumination are disclosed herein. An example method includes detecting, by a microprocessor, a presence of an aim light pattern within the FOV; determining, by the microprocessor and in response to the detecting, a target distance of an object in the FOV based on a position of the aim light pattern in the FOV, the target distance being a distance from the imaging engine to the object; causing, by the microprocessor, a variable focus optical element to focus on the object based on the target distance; responsive to making a first determination, by the microprocessor, selecting, based on the target distance, one of a plurality of zoom operation modes; and responsive to making a second determination, by the microprocessor, selecting, based on the target distance, one of a plurality of illumination modes.

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: The optical assembly further includes an actuator physically coupled to the front lens group that adjusts the position of the front lens. A rear lens group is disposed along the optical axis to receive the light from the front lens group, and an imaging sensor is disposed at a back focal distance of the rear lens group, to detect the light.

Abstract: 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.
