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.

摘要： A unitary body of optical material and associated methods for reading indicia such as bar codes is provided. The unitary body can focus light from a light source into a beam, redirect light reflected from a target to a photodetector, and provide mechanical support for a light source, printed circuit board, or other indicia reader components. In comparison to conventional apparatus, the unitary body requires a reduced number of components and is therefore easier and less expensive to manufacture and assemble. The unitary design increases reliability and performance consistency while decreasing sensitivity to thermal and mechanical loading. Moreover, the unitary body reduces the overall tolerance budget of a reader and therefore facilitates mass production of optical apparatus and readers. The unitary body and associated methods may be implemented in a compact reader with the aforementioned advantages in the form of a pen, or can be integrated into an antenna of a wireless device, such as a cell phone or a PDA.

摘要： Holographic optical elements are configured and deployed in optical imagers and scanners to produce optical modification of output laser beams and light received and detected by the system. In some preferred embodiments electrically switchable holographic optical elements (ESHOEs) are employed for beam tilting, for varying spot size and shape for modifying system focal distance and field of view, for changing laser aiming patterns and/or for color imaging.

摘要： An imaging-based bar code reader that includes an item guide to guide movement of an item including a target bar code such that target bar code passes through a field of view of the reader in a straight line. The reader further includes an imaging and decoding system to: 1) capture a series of images which include at least a part of the target bar code as the bar code is moved through the field of view of the reader; 2) sequentially analyze the series of captured images, for each captured image, identifying areas of the captured image representative of an image of the target bar code and decode decodable portions of the imaged target bar code; and 3) combining the decoded portions of the imaged target bar code using a sequence stitching method to obtain a full decode of the target bar code.
