摘要： An apparatus and method for imaging a target, includes a housing having a presentation area, a solid-state imaging sensor having an imaging array of image sensors looking at a field of view that extends through the presentation area to the target, and an imaging lens assembly for capturing return light over the field of view from the target through the presentation area, and for projecting the captured return light onto the imaging array during imaging of the target. The assembly has a plurality of lenses, an aperture stop, and a holder for holding the lenses and the aperture stop in spaced relation along an optical axis. The aperture stop has a non-rotationally symmetrical aperture through which the optical axis extends. Alignment elements on the imaging lens assembly are used to align the non-rotationally symmetrical aperture with the imaging array.

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.

摘要： A laser power control arrangement and method in an electro-optical reader for reading indicia includes an energizable laser for emitting a laser beam having an output power along a path. An internal light detector, e.g., a monitor photodiode, is mounted inside the laser for monitoring the output power of the laser. An external light detector, e.g., an auxiliary photodiode, is mounted outside the laser for monitoring the output power of the laser independently of the internal light detector. A guide, advantageously a light pipe or a diffuser, is positioned outside the laser in the path of the laser beam for guiding the laser beam from the laser to the external light detector. A controller is operatively connected to each light detector, for controlling a monitored output power of the laser beam by deenergizing the laser when the monitored output power of the laser beam exceeds a safe power level limit.
