摘要： A module and an arrangement for, as well as a method of, generating a generally uniform distributed line pattern of light on a symbol to be read by image capture, include a light source for generating light along an optical axis in a distribution having different extents along intersecting directions generally perpendicular to the axis, and an optical component for receiving, and for optically modifying, the light from the light source to generate the generally uniform distributed line pattern of light on the symbol. The optical component includes a plurality of compound conic elements spaced apart from one another along one of the directions. Each compound conic element has a pair of conic segments for modifying the light along the one direction. A collimating lens modifies the light along the other of the directions. A solid-state imager has an array of image sensors for capturing return light from the symbol over a field of view having different extents along the intersecting directions.

摘要： A method and apparatus for improving the image quality obtained by an imaging-based scanner comprising a housing supporting one or more protective windows. The apparatus further comprises at least one scanning arrangement, the scanning arrangement comprising illumination and imaging optics. The illumination and imaging optics form a respective field of view for imaging a target object. A light baffle is attached to the scanning arrangement. The light baffle has an aperture corresponding to each of the illumination and imaging optics such that stray light reflected from the protective windows is absorbed by the light baffle, improving the image quality of the imaging-based scanner.

摘要： A compact hybrid imaging lens assembly captures return light from a target over a field of view of a linear array of image sensors of a solid-state imager, and projects the captured return light onto the array during electro-optical reading of the target. The assembly includes a plastic lens for optical aberration correction, a glass lens spaced away from the plastic lens along an optical axis, and an aperture stop between the lenses and having an asymmetrical aperture through which the optical axis extends. The glass lens has substantially all the optical power of the imaging lens assembly for thermal stability, and the plastic lens has substantially no optical power. A holder holds the lenses and the aperture stop away from the array. Alignment elements on the plastic lens align the asymmetrical aperture relative to the linear array.

摘要： A method and imaging assembly (10) are disclosed adapted for reading a target object comprising a scan engine (48) having a sensor (46), focusing optics (44), and an imager (48). The scan engine includes a field-of-view defining an area to be imaged by the imaging assembly (10). A housing (80) internally lodges the scan engine (48) and an illumination source (36). The illumination source (36) is adapted to project illumination from the housing (80). A boot (30) extends from the housing (80) for shaping the illumination as it passes through the boot to form an illumination pattern from the illumination. The illumination pattern substantially conforms to a geometrical shape of the boot (30) and is adapted to envelope the scan engine field-of-view.
