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; and responsive to making a first determination, by the microprocessor, selecting, based on the target distance, one of a plurality of zoom operation modes.

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: Multiple focus ball bearing actuator calibration is disclosed herein. An example method includes focusing, using a ball bearing actuator, a lens to a first focus position to image a first target; recording, in a lookup table, a first distance and a first actuator code corresponding with the first focus position; focusing the lens to a second focus position to image a second target; recording, in the lookup table, a second distance and a second actuator code corresponding with the second focus position; calculating a plurality of focus positions for a plurality of distances over a total working range of the barcode reader using the first focus position and the second focus position, wherein the calculating is performed without a temperature correction factor; and recording, in the lookup table, the plurality of distances and a plurality of actuator codes corresponding to the plurality of focus positions.

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: 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: 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.
