    Abstract: Methods and apparatus for configuring reduced decode ranges for barcode scanners are disclosed. An example method includes determining a closest focus distance of a plurality of focus distances at which a barcode placed at a furthest limit of a reduced decode range can be successfully decoded; determining a furthest focus distance of the plurality of focus distances at which the barcode placed at a closest limit of the reduced decode range can be successfully decoded; determining a subset of the plurality of focus distances that consists of the closest focus distance, the furthest focus distance, and focus distances between the closest focus distance and the farthest focus distance; and configuring the barcode scanner to only use the subset of focus distances during subsequent attempts to decode barcodes.

    IPC: G06K7/10

    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 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.
