摘要： A method of imaging a target object with an imaging reader. The method includes the following: (1) detecting light from the target object through a lens arrangement with an image sensor to generate light-field data; (2) generating a stream of image data including image data representing an expected in-focus image of the target object, and (3) processing the expected in-focus image of the target object to decode a barcode on the target object. The image sensor includes an array of photosensitive elements and an array of microlenses that overlays the array of photosensitive elements located at a focus plane of the microlens.

摘要： The disclosed bar code reader includes an auto-focusing component for rapidly producing in focus images. An imaging system makes use of an aiming pattern that impinges upon the coded indicia of a target. The imaging system includes a light monitoring pixel array and a focusing lens that is fixed with respect to the pixel array for transmitting an image of the target object onto the pixel array. The imaging system also includes a movable mirror mounted for movement along a path of travel to reflect light passing through the focusing lens onto the pixel array. A drive motor moves the mirror relative the lens to adjust a focus of an image of the object formed at the pixel array. An automatic focusing component of the imaging system analyzes the aiming pattern reflected from the target object and projected onto the pixel array by the lens. The automatic focusing component issues commands to the drive motor causing the mirror to move along its path of travel to a suitable position for properly focusing the target object onto the pixel array.

摘要： An optical scanner such as a bar code scanner includes a segmented fold mirror, the individual sections of which have different profiles. By directing the scanning laser beam across the fold mirror, a plurality of scan lines are created, at different distances from the scanner. This provides increased flexibility by extending the scanner's working range. In alternative embodiments, a collector mirror and/or a scanning mirror may be segmented. In addition, beam shaping may be provided by reflecting the beam from one or more aplanar surfaces.

摘要： A method includes capturing an image of a target object within a field of view through an imaging lens arrangement with an imaging sensor during a frame exposure time period in rolling shutter mode. The method further includes activating an aiming light source to generate a visible aiming light pattern towards the target object during a part of the frame exposure time period and to substantially deactivate the aiming light source during the remaining part of the frame exposure time period.

摘要： Electro-optical reading failure to read indicia due to specular reflection in the return light captured by a solid-state imager is prevented. An illuminator illuminates the indicia during reading with illumination light directed from an illuminating light source. In one embodiment, a controller is operative for detecting saturation in a captured image, and for reducing an intensity of the illumination light upon detection of the saturation. In another embodiment, the controller captures the return light in successive frames, and causes the illumination light to illuminate the indicia only during some of the frames. In yet another embodiment, the controller turns the illumination light on and off at a flash rate, and signals a user by changing the flash rate upon detection of the saturation to move a housing that supports the imager, illuminator and controller.
