    • An extended working range electro-optical scanner for reading a barcode is described. The scanner includes a scan engine including a beam assembly for repetitively directing a beam of light at a scan angle across the barcode and an array of non-imaging light collectors for collecting and concentrating reflected light from the barcode. Each light collector of the array of light collectors includes entrance and exit apertures. A total area of the entrance apertures of the array of light collectors is greater than 50% of a total area of a target-facing surface of the scan engine. Each of a corresponding array of photodetectors is positioned at an exit aperture of a respective light collector of the array of light collectors to receive concentrated light from its respective collector and generates an output electrical signal corresponding to an intensity of the concentrated light received by the photodetector.
    • 描述了用于读取条形码的扩展工作范围电光扫描器。 该扫描器包括扫描引擎,该扫描引擎包括用于以条形码扫描的角度重复地引导光束的束组件和用于收集和集中来自条形码的反射光的非成像光收集器的阵列。 集光器阵列的每个集光器包括入口和出射孔。 集光器阵列的入射孔的总面积大于扫描引擎的面向目标表面的总面积的50%。 相应的光电检测器阵列中的每一个都位于集光器阵列的相应光收集器的出射孔处,以从其相应的集电极接收集中的光,并产生对应于由光电检测器接收的集中光的强度的输出电信号 。

    • A bi-optical, dual window, point-of-transaction workstation images indicia associated with multi-sided products over a full coverage scan zone by asymmetrically splitting the field of view of at least one imager into light collection regions of different spatial volumes. The light collection regions fill the scan zone and minimize dead areas therein. A smaller light collection region images one side of the product, while a larger light collection region images more than one side of the product. All sides of the product are imaged in the light collection regions. Twisting of the light collection regions relative to at least one of the windows is minimized so that the light collection regions fit fully with minimal clipping through each window. Illumination light is directed away from a user's eyes.
    • 双光学双窗口交易点工作站通过将至少一个成像器的视场不对称地分割成不同空间体积的光收集区域,在全覆盖扫描区域上与多面产品相关联的图像标记。 光收集区域填充扫描区域并使其中的死区最小化。 较小的光收集区域成像产品的一侧,而较大的光收集区域成像多于一侧的产品。 产品的所有侧面都在光线收集区域成像。 使光收集区域相对于至少一个窗口扭曲被最小化,使得光收集区域以最小限度穿过每个窗口的方式完全配合。 照明光指向远离用户的眼睛。
