    摘要: Embodiments of the disclosure relate generally to flicker reduction in a multi-imager environment. Embodiments include methods, computer program products, and apparatuses for producing a near-field illumination using a near-field illuminator, the near-field illumination produced at a defined pulse train. A near-field image sensor may be exposed near the start of a near-field illumination pulse, and a far-field image sensor may be exposed between pulses of the near-field illumination. Some embodiments, additionally or alternatively, are configured for detecting an illuminator switch event, deactivating the near-field illuminator source, and producing, using a far-field illuminator source, a far-field illumination. Upon switching the illuminator source, some such embodiments are configured for exposing a far-field illuminator near the start of the far-field illumination pulse, and exposing a near-field image sensor near the start of the next available far-field illumination pulse. Such image capture may repeat until a task such as barcode reading is successful.

    摘要: Optical assembly, imaging reader, and method for dual-lens illumination are provided. For example, an example optical assembly may include first and second light sources, first and second collection lenses positioned and shaped to collect light emitted by the first and second light sources and transmit the collected light with reduced divergence, first and second pattern-shaping apertures positioned to allow at least a portion of the light transmitted by the first and second collection lens to pass therethrough, and first and second projection lens positioned to receive the light transmitted by the first and second collection lenses and passed through the first and second pattern-shaping apertures. The projection lenses are shaped to project the received light into the field of view of an imaging system with a higher intensity at a lateral side edge of the light projected and a lower intensity at a medial side edge of the light projected.
