摘要： A bar code scanning system and method for reading and processing bar code symbology uses a scanning station installed above the check-out stand and a receiving station at some distance away from the scanning station. The scanning station projects light onto a surface of the check-out stand. The projected light can have a well defined border indicating where a user should place items to be scanned. Alternatively, a pattern coincident with the projected light can be projected onto the surface and which includes a target indicating where items should be placed for scanning. Light reflected by items in the target region is processed to decode optical symbology on the item and produce a signal that is representative of said sensed symbology. Information about the scanned item can be processed and displayed by the receiving station for use in, e.g., a point-of-sale transaction. The system can also be configured to capture images of a user's payment card for use in payment processing and to store images of at least selected scanned items for use in subsequent processes.

摘要： A miniature imager for reading target images. The optical and electrical systems of the miniature imager are optimized to reduce one or more dimensions or the volume of the imager. In accordance with one embodiment the pixel pitch and focal length are decreased for that of a larger imager to maintain a comparable field of view for each pixel. The decreased pixel pitch allows the area of the aperture and the instantaneous field of view of the pixel to remain constant while decreasing the overall size of the imager. In other embodiments apparatus and techniques reduce and/or eliminate the need for illumination of a target by the imager thereby reducing the overall power consumed by the imager and/or its overall size. The imager has an increased working range.

摘要： A semi-retroreflective optical scanning system has an optical scanning element which directs a scanning light beam via a stationary holographic optical element in a scan path across indicia to be read. Light from the indicia is collected by an optical collector, such as a lens or a mirror, which focuses it onto a small optical detector via the scanning element. The field of view of the optical detector scans across the indicia in synchronization with the outgoing scanning beam from the holographic optical element. Since the incoming reflected light is not limited by the aperture of the scanning element, the signal-to-noise ratio remains high even when a small scanning element is used. In a further embodiment the light source, scanning element collector and detector are provided in a common plane, the collector and scanning element sharing a common optical axis and a light source being provided substantially off axis to allow reduction in the scanning element size. In a further aspect of the invention a solid state reader is provided capable of establishing the distance to the target by sensing the exact position on the detector at which the target is imaged. According to yet a further aspect of the invention the problem of specular blinding is overcome by providing a plurality of sensors activated in a dynamic on-off sequence, for example a random sequence.
摘要翻译：半回光光学扫描系统具有光学扫描元件，其通过经过待读取的标记的扫描路径中的静止全息光学元件引导扫描光束。来自标记的光由诸如透镜或反射镜的光学收集器收集，其通过扫描元件将其聚焦到小型光学检测器上。光学检测器的视野与来自全息光学元件的输出扫描光束同步地扫描标记。由于入射的反射光不受扫描元件的孔径的限制，即使使用小的扫描元件，信噪比也保持较高。在另一个实施例中，光源，扫描元件收集器和检测器设置在公共平面中，集电器和扫描元件共享公共光轴，光源基本上设置在离轴上，以允许减小扫描元件尺寸。在本发明的另一方面，提供了一种固态读取器，其能够通过感测检测器上目标物被成像的确切位置来建立与目标的距离。根据本发明的另一方面，通过提供在动态开关序列（例如随机序列）中激活的多个传感器来克服镜面盲法的问题。
