Abstract: A mark reader apparatus has a lens and an autofocus system that manipulates the lens in accordance with control signals. An image acquisition system measures a distance from the lens to a dot peened mark. A processor is programmed to: calculate a focus position for the autofocus system that focuses the lens on the dot peened mark; apply an offset to the calculated focus position to produce an offset focus position; control the autofocus system by positioning the autofocus system to the offset focus position; and via the image acquisition system, acquire an image of the mark with the autofocus system set to the offset focus position.

Abstract: Systems and methods for minimizing laser persistence are provided. In one implementation, a timing circuit for controlling a barcode reader is provided. The timing circuit comprises a shutter control circuit configured to control an electronic shutter function of an image sensor and a laser control circuit configured to control the activation of a reference laser. When activated, the reference laser directs a laser beam to an approximate position of a field of view of the image sensor. The activation of the reference laser includes a delay to minimize laser persistence on an image captured by the image sensor.

Abstract: A process is disclosed for scanning a graphic medium scan target. An image of the scan target is captured over an exposure duration. An illumination of the scan target is actuated over an illumination duration brief relative to the exposure duration. The illumination of the scan target is deactivated upon an expiration of the illumination duration. The capturing the image step continues over a significant portion of the exposure duration persisting after the expiration of the illumination duration.

Abstract: A reader obtains image data corresponding to an image of optically encoded information that is received via a lens unit that causes controlled spherical aberration blurring that is precisely known. The reader may perform deconvolution processing on the image data to render it decodable. The deconvolution processing may implement a Weiner filter that uses data corresponding to a near-field point spread function of the lens unit. The depth of field of the reader is greater than that of conventional reader in all lighting conditions.

Abstract: An automatic data collection device includes an automatic focusing feature. The automatic focusing feature is based on a type of triangulation technique, which determines an optimum position of an imaging lens in order to obtain an optimally focused image. The position of the imaging lens may be adjusted until the imaging lens is at the optimum position. A pair of aiming beams is separated by a distance. The optimum position of the imaging lens (and/or the amount of displacement of the imaging lens that is needed to reach the optimum position) can be determined based on a relation that involves the distance between the two aiming beams, a focal length of the imaging lens, and a distance between “spots” that are respectively generated on an image plane (such as on an image sensor) by the pair of aiming beams.

Abstract: An automatic data collection device is provided for reading barcodes, matrix codes, stacked codes, or other machine-readable symbol. The data collection device generates an aiming beam that serves a dual purpose of target locating and data acquisition, such as data acquisition using imaging methods. The aiming beam defines the field of view of the data collection device for imaging. The illumination pattern provided by the aiming beam for imaging can have its shape, size, and/or intensity adaptively changed depending on conditions.
