摘要： A bioptical workstation includes plural image capture modules for capturing images of indicia along different fields of view. Each module includes an illuminator for illuminating the indicia with illumination light, a megapixel imager with a rolling shutter for sequentially capturing the return light, and a shutter element for passing the return light to its imager in an open state, and for blocking the return light from other modules from reaching its imager in an closed state. A controller prevents interference among the modules by controlling the shutter element to assume the open state only during a respective exposure time period during which its imager produces an electrical signal indicative of the indicia, and by controlling the shutter element to assume the closed state at all times other than the respective exposure time period to prevent capture of the return light from the other modules.

摘要： A bi-optical, dual window, point-of-transaction workstation images indicia associated with multi-sided products over a full coverage scan zone by splitting each field of view of only two imagers into three subfields that pass through each window and fill the scan zone and minimize dead areas therein. Twisting of the subfields relative to the windows is minimized so that the subfields fit fully with minimal clipping through each window. Splitting of each field of view is remotely performed well away from each imager. The imagers have lens assemblies of substantially the same optical power and are spaced from their respective windows by substantially the same distance.

摘要： An imaging reader for, and a method of, imaging targets, include a solid-state imager supported by a housing for capturing return light from a target over a field of view. An illumination light assembly performs both illumination and aiming functions. Illumination light is projected along an optical path through a passage in the housing to illuminate the target. The housing has boundary walls spaced along the optical path away from the imager and the illumination light assembly for clipping the illumination light projected through the passage to form on the target an aiming light distribution that visually indicates a periphery of the field of view to assist in positioning the target entirely within the field of view.

摘要： A laser scanner includes a laser, a variable focusing element, a scanner, a detector, and a controller that controls the scanner to sweep a laser beam over an aiming angle at an aiming rate to form an aiming line on a symbol during aiming, and over a reading angle at a reading rate to form a reading line on the symbol during reading that follows the aiming. The aiming angle is smaller than the reading angle. The aiming rate is higher than the reading rate. The aiming line is shorter than the reading line. The controller determines a depth of modulation of an analog signal generated during aiming, and controls the variable focusing element to focus the laser beam on the symbol during aiming when the depth of modulation is determined to be optimum. The controller also processes the analog signal to data indicative of the symbol during reading.

摘要： A plurality of solid-state imagers is mounted in a reader, such as a bioptical, dual window, point-of-transaction workstation, for capturing illumination light returning along different fields of view from indicia. A controller controllably activates the imagers over respective exposure time periods during which the indicia are illuminated to produce electrical signals indicative of the indicia being read, processes the electrical signals to read the indicia, and controls the exposure time periods to be nonconcurrent to prevent interference among the imagers.
