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: 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: Method and systems for driving an aiming assembly of a barcode imager are provided. An example method includes obtaining an operating mode of the barcode imager having an aiming assembly and, in response, determining a duty cycle of an aiming pulse of the aiming assembly. That duty cycle is determined as a percentage of a frame duration of an imager sensor and, further, such that simultaneous constraints are satisfied by the aiming pulse. The constraints include a simultaneous frame duration-independent, peak pulse optical power constraint and a frame duration-dependent heat dissipation constraint.
