    摘要： An optical reader for reading indicia such as bar codes comprises a first and second light source for generating first and second laser beams. The respective laser sources generate light at different wavelengths and a dichroic filter is provided to allow either source to be used without parallax effects. The laser scanner beam can be used to aim the reader when carrying out field of view reading. The optical reader is further provided with a band-pass filter shaped to match the wave-front of light generated at a given location incident on the filter to reduce the band-pass bandwidth and hence the ambient noise. The shaped band-pass filter can be incorporated in the optical reader dichroic filter arrangement.

    摘要： An optical reader for reading indicia such as bar codes comprises a first and second light source for generating first and second light beams of mutually orthogonal polarization orientations, and a polarized beam splitter for combining the beams without the effects of parallax or vignetting. One of the light sources is a short range light source and the other is a long range light source. The reader may be a scanner or a field of view reader. In addition, an optical reader is provided capable of reading all 2D symbologies comprising a flying spot laser scanner arrangement and a field of view reader. The respective laser sources generate light at different wavelengths and a dichroic filter is provided to allow either system to be used without parallax effects. The laser scanner beam can be used to aim the reader when carrying out field of view reading. An optical reader is further provided including a band-pass filter shaped to match the wave-front of light generated at a given location incident on the filter to reduce the band-pass bandwidth and hence the ambient noise. The shaped band-pass filter can be incorporated in the optical reader dichroic filter arrangement.

    摘要： A miniaturized electro-optical, retro-reflective scanning module. The module has a base, a first circuit board, and a second circuit board mounted substantially orthogonal to the first circuit board. The base supports a light emitter for producing a scanning beam and optical elements for directing and collecting light energy. The emitted beam reflects off a fold mirror onto a reflector mounted on a drive for oscillation. The oscillating reflector, in turn, redirects the beam onto an indicia being read. The reflected light is reflected off the oscillating reflector and directed to the collection mirror before reaching a detector. The detector included in the module senses light reflected from an indicia scanned by the beam. The reflector is driven by an electro-magnetiz driven system, including a flexure and an actuation arm.

    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.
