  • Patent number: 8083147
    Abstract: An arrangement for, and a method of, controlling image exposure in an imaging reader for reading symbols, employ an illuminating light assembly for illuminating a symbol with illumination light, a solid-state imager for capturing return light from the symbol over a field of view, and a controller for successively exposing the imager over a first exposure time period to capture the return light from, and to optimally image, a first area of the symbol, and over a second exposure time period to capture the return light from, and to optimally image, a second area of the symbol. The first and the second areas have different light intensity levels. The first and the second exposure time periods are different in duration. The controller is operative for combining the optimally imaged first and second areas to read the symbol.

  • Publication number: 20110297853
    Abstract: A substantially uniform distributed illumination pattern of light is generated on and along a symbol to be read by image capture. A solid-state imager is mounted on a tilted printed circuit board in a tilted handle of an ergonomic reader. An imaging lens assembly captures return light over a field of view from the symbol along an imaging axis, and projects the captured return light onto the imager. An illumination light source is mounted on the board for emitting illumination light at an acute angle of inclination relative to the imaging axis. An optical component includes a first lens portion with a polynomial incident surface for intercepting, bending and aligning the emitted illumination light to generate the pattern in a scan direction along the symbol, and a second lens portion with a toroidal or cylindrical aspherical surface for collimating the aligned illumination light to generate the pattern in a transverse direction.

  • Publication number: 20110290886
    Abstract: The exemplary bar code reader has an auto-focusing component positioned between a photo-detector array and an object having target indicia. The auto-focusing component has a lens system for focusing the target indicia at an imaging plane that generally co-incides with a plane of the photo-detector array. An electromagnetic coil actuator is coupled to an adjustable aperture such that activation of the coil actuator moves the adjustable aperture into and out of the imaging field of view to adjust a focusing on the target indicia. The autofocus component is fixed when the moveable aperture is within the field of view for focusing on objects close to the reader and when the aperture is removed, the autofocus is effective in imaging objects at a greater distance from the reader.
