摘要： Indicia are imaged at a workstation having windows arranged in intersecting planes. The workstation also has solid-state imagers with fields of view that are split into intersecting subfields that look out through the windows, as well as illumination assemblies each having multiple light sources that illuminate each subfield with illumination light over an illumination field that overlaps a respective subfield. Light-modifying elements, such as lenses or baffles that are radially offset from the multiple light sources, condition the illumination light from the multiple light sources to be generally uniform in light intensity over at least one illuminated subfield.

摘要： A bi-optical, dual window, point-of-transaction workstation images indicia associated with multi-sided products by splitting the field of view of each imager into a plurality of subfields that simultaneously extend through each window over regions of the product. A plurality of energizable illuminators, one for each subfield, illuminates each subfield with illumination light over an adjustable illumination time. The illumination light returned from the indicia in each subfield is captured along respective optical paths from each window to each imager. A plurality of exposure sensors, one for each subfield, and located externally of each imager, senses the returned illumination light in each subfield. A controller energizes each illuminator to illuminate each subfield, deenergizes each illuminator when the returned illumination light sensed by the respective exposure sensors exceeds a threshold, and processes the captured illumination light in at least one of the subfields.

摘要： An apparatus for and method of electro-optically reading targets arbitrarily oriented in a workstation, such as a dual window workstation, employs a solid-state imager for capturing return light from the targets over a field of view. The imager has an array of sensors arranged along mutually perpendicular array axes. An optical system splits the field of view into a plurality of subfields of view that extend through a workstation window to a target. One subfield is optically configured to enable the imager to capture light from the target along one array axis. Another subfield is optically configured to enable the imager to capture light from the target along the other array axis. A controller processes the captured light in both the one and the other subfields to enable the reading of the arbitrarily oriented target in the workstation independently of target orientation relative to the array axes.

摘要： A method and apparatus for reading optical indicia. The method includes generating calibration light, and measuring an intensity of the calibration light reflected into a detector system. The method also includes determining an optimum exposure level for the imaging system based on the measured intensity of the calibration light reflected into the detector system, and generating an illumination light with an illumination system. In addition, the method includes capturing an image of the optical indicia with the imaging system subjecting to the optimum exposure level.

摘要： A checkout system employs a bi-optical workstation having dual windows and a main reader for electro-optically reading indicia on products to be processed at the workstation through at least one of the windows. The workstation is supported by a countertop and has a raised housing extending upwardly away from the countertop. An auxiliary cordless reader is used for electro-optically reading the indicia in a handheld mode when the main reader is not operated. A cradle bounds a compartment in which the auxiliary cordless reader is removably received when not in the handheld mode. The cradle is supported by the raised housing above and remote from, and out of direct contact with, the countertop to form a zero-footprint therewith.
