摘要： The disclosed bar code reader includes an auto-focusing component for rapidly producing in focus images. An imaging system makes use of an aiming pattern that impinges upon the coded indicia of a target. The imaging system includes a light monitoring pixel array and a focusing lens that is fixed with respect to the pixel array for transmitting an image of the target object onto the pixel array. The imaging system also includes a movable mirror mounted for movement along a path of travel to reflect light passing through the focusing lens onto the pixel array. A drive motor moves the mirror relative the lens to adjust a focus of an image of the object formed at the pixel array. An automatic focusing component of the imaging system analyzes the aiming pattern reflected from the target object and projected onto the pixel array by the lens. The automatic focusing component issues commands to the drive motor causing the mirror to move along its path of travel to a suitable position for properly focusing the target object onto the pixel array.

摘要： An image scanning device is provided which includes a system for determining the distance to a target to be scanned. The image scanning device includes an optical system and an image sensor array 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： A portable electro-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.
