摘要： A portable electo-optical scanner for reading a target bar code having a plurality of bar code elements. The portable scanner includes: a housing supporting a scanning module and an optic system. The scanning module electro-optically scans the target bar code with a scanning beam and collects reflected light returning from the bar code. The scanning module includes a beam source emitting a scanning beam, beam directing apparatus causing the scanning beam to be repetitively scanned along a scanning plane intersecting the target bar code and photodetector circuitry receiving light from the target bar code. The optic system includes an exit window, a light collection lens and a reflective surface. The scanning beam passes through the exit window upon exiting the housing. The light collection lens receives reflected light from the target bar code and directing the reflected light toward a focal point. The focal point lying on the scanning plane of the scanning beam. The reflective surface is disposed between the light collection lens and the focal point to redirect the reflected light passing through the light collection lens toward the photodetector circuitry.
摘要翻译：一种用于读取具有多个条形码元素的目标条形码的便携式电光扫描器。便携式扫描器包括：支撑扫描模块和光学系统的壳体。扫描模块用扫描光束电光扫描目标条形码并收集从条形码返回的反射光。扫描模块包括发射扫描光束的光束源，引导扫描光束沿着与目标条形码相交的扫描平面重复扫描，光电检测器电路从目标条形码接收光。光学系统包括出射窗，光收集透镜和反射表面。扫描光束离开外壳后通过出射窗。光收集透镜从目标条形码接收反射光并将反射光引向焦点。焦点位于扫描光束的扫描平面上。反射表面设置在光收集透镜和焦点之间，以将通过光收集透镜的反射光重定向到光电检测器电路。

摘要： An image scanning device (12) is provided which includes a system (404, 604) for determining the distance (Zo) to a target to be scanned. The image scanning device includes an optical system and an image sensor array (403, 603) for focusing a light beam and imaging the target. The device preferably includes an automatic focusing system for adjusting the position of the optical system in order to adjust the focal point, and thereby focus the image of the target onto the image sensor array. In one embodiment of the image scanning device, the distance is determined by analyzing a collimated aiming pattern formed by collimating the light beam. In another embodiment, the distance is determined by analyzing a speckle pattern caused by the speckle effect upon the light beam hitting the target.
摘要翻译：提供一种图像扫描装置（12），其包括用于确定与待扫描的目标物的距离（Zo）的系统（404,604）。图像扫描装置包括光学系统和用于聚焦光束并对目标成像的图像传感器阵列（403,603）。该装置优选地包括用于调整光学系统的位置以便调整焦点的自动聚焦系统，从而将目标的图像聚焦到图像传感器阵列上。在图像扫描装置的一个实施例中，通过分析通过准直光束形成的准直瞄准图案来确定距离。在另一个实施例中，通过分析由光束撞击目标物上的斑点效应引起的散斑图案来确定距离。
