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： An optical scanning system for reading indicia of differing light reflectivity has an optical scan module which is adapted to be mounted on a finger of a user. A first peripheral module, preferably in the form of a wrist watch, has a receiver which detects the reflected light. A second peripheral module, mounted on the other arm of the user, communicates with the first module by radio frequency transmission. According to other aspects of the invention, the light detector may be mounted in a housing which is separate and part from the optical scan module. According to another aspect, a laser pointer or scanner is mounted to a ring which is arranged to be worn on a single finger of the user.

摘要： An optical collector collects relatively more of the off-axis light directed to a detector, and collects relatively less of the on-axis light directed to the detector, in order to decrease the variation in the amplitude of the electrical signal generated by the detector over a scan of target such as a bar code symbol in order to improve the performance of a bar code symbol reader.

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.
