摘要： An optical aberration is intentionally introduced into the optical system which produces the scanning beam of an optical code scanner, in order to produce a scanning beam which has plural focal points or waists at different distances from the scanner. The operating range of the scanner can thereby be increased by taking advantage of different beam waist locations when the optical code is at different distances from the scanner. In accordance with an embodiment of the invention, coma is intentionally introduced to an optical system providing a light beam for an optical code scanner. This provides a scanning beam with plural beam waists at different distances from the scanner. This may be accomplished by orienting the light source and focusing optical system so that their optical axes intersect or by introducing an optical member, such as a prism, between the original light source and the focusing optical system.
摘要翻译：有意地将光学像差引入到产生光学代码扫描器的扫描光束的光学系统中，以便产生具有与扫描仪不同距离的多个焦点或腰部的扫描光束。因此，当光学代码与扫描仪不同的距离时，通过利用不同的光束腰部位置可以增加扫描仪的操作范围。根据本发明的实施例，有意地将彗差引入到为光学代码扫描器提供光束的光学系统中。这提供了具有与扫描器不同距离的多个波束腰的扫描光束。这可以通过使光源和聚焦光学系统定向使得它们的光轴相交或者通过在原始光源和聚焦光学系统之间引入诸如棱镜的光学构件来实现。

摘要： A changeable apparatus for scanning a symbol is disclosed wherein by selectively changing the position of a bending mirror (101), different scan patterns are produced. In a preferred embodiment, the different positions of the bending mirror (101) result in a scanning beam (107, 108) being directed off of different polygon scanning mirrors (104, 105) to create the different scanning patterns.

摘要： A variable focus illumination system includes a light source which projects light forwardly, in the path of the light from the source, a movable lens forward of the light source which is mounted for axial movement towards and away from the light source, and a stationary lens is mounted forward of the moving lens. By design, the lens combination creates an image of the light source which is rearward of the actual light source, and movement of the movable lens focuses the light projected forwardly from the image. In comparison to a single lens system, in this dual lens system, the positioning accuracy required in the moving lens in order to achieve a given positional accuracy of focus may be an order of magnitude lower. In accordance with another aspect of the invention, the movable lens is formed as a unit with an opposed, spaced aperture of fixed diameter.

摘要： A method and apparatus is disclosed that uses a two dimensional image sensor to read a one dimensional symbol such a barcode. The one dimensional barcode is imaged using a selected set of rows of the two dimensional image sensor, and corresponding positions in the selected rows are then averaged. The single sequence of averaged values is then converted to a run length code to decode the associated data. The number and location of rows of elements of the two dimensional sensor that are used may be varied to adjust various characteristics of the reader.

摘要： A compact barcode reader is provided in which the imaging lens and a linear sensor are in a straight line path with the barcode (no bend in path). By using a wide angle lens with a short back focus, it is possible to reduce the distance between the barcode and linear sensor to a fraction of what it was in the prior art. In addition, the maximum image height and the downward projection of the sensor are reduced to a fraction of what they were in the prior art. As a result, despite the straight line optical path, compact barcode reader becomes so small that it does not interfere with the operation of the beverage maker.
摘要翻译：提供了一种紧凑的条形码读取器，其中成像透镜和线性传感器处于与条形码的直线路径（路径中没有弯曲）。通过使用具有短后焦距的广角镜头，可以将条形码和线性传感器之间的距离减小到现有技术中的一小部分。此外，传感器的最大图像高度和向下投影减小到现有技术中的一小部分。结果，尽管直线光路，紧凑的条形码读取器变得如此之小，使得它不干扰饮料制造机的操作。
