The present disclosure describes methods and systems for reducing perceived flickering in multi-sensor barcode scanners. The proposed solution introduces a dummy illumination pulse during transitions between sensors or frames, mitigating noticeable flicker. The timing, duration, and spacing of the dummy pulse are calculated based on factors such as the next expected exposure, frame rate, and/or previous exposure. This solution can be applied to a variety of barcode scanners, including those with different sensors for near and far scanning or those using different LEDs for capturing frames. The system also potentially includes an illumination boost circuitry that recharges during the generation of the dummy illumination pulse, preventing system faults. The method offers an effective solution to illumination flicker in multi-sensor barcode scanners without causing unnecessary delays or system errors.

Techniques for automated beam adjustment for portal directionality are disclosed herein. An example apparatus includes: a transceiver configured to emit a plurality of signal beams that each have a respective coverage area and are oriented in a respective direction, one or more processors, and one or more memories communicatively coupled to the one or more processors storing a beam adjustment algorithm. The example apparatus may include instructions that, when executed cause the assembly to: transmit a first signal beam to a set of tags located within a first respective coverage area of the first signal beam while the first signal beam is oriented in a first direction; determine, by the beam adjustment algorithm, that a first tag threshold is violated; and adjust, by the beam adjustment algorithm, an orientation of the first signal beam from the first direction to a second direction.

A code reader may include a light source configured to illuminate a target area in which items are to be located for reading machine-readable indicia associated with the items, an image sensor configured to capture an image of the target area, an illumination drive circuit in electrical communication with the light source, and an image capture circuit. The image capture circuit may be configured to (i) enable and disable the image sensor to capture an image of the target area during the high illumination and a portion(s) of the low illumination of the target area, and (ii) read an image captured by the image sensor. The illumination drive signals may cause the illumination drive circuit to generate a high illumination drive signal to cause the light source to produce a high illumination, and generate a low illumination drive current to cause said light source to produce a low illumination.
