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： 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： An optical-information-reading apparatus includes an imaging optical system having a varifocal lens that adjusts a focal position, a solid-state image sensing device that images a code symbol, a ranging laser that measures a distance to the code symbol, and a decoder that calculates the distance to the code symbol using the ranging laser. The apparatus controls the varifocal lens based on calculated distance information.
