    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.

    摘要: 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.

    摘要: An electro-optical imaging reader includes a chassis mounted in a housing, a window spaced from a rear wall of the chassis, an imaging module for capturing return light from a target through the window over an imaging field of view, a controller for operating the reader in a standby state in which no target is read, and for processing the captured return light to read the target during a reading state, and an object sensing assembly supported by the rear chassis wall and spaced from the window. The object sensing assembly senses the presence of an object bearing the target in front of the window by detecting return sensing light from the object through the window over a sensing field of view that at least partially overlaps the imaging field of view, and triggers the controller to change from the standby state to the reading state upon such detection.

    摘要: A workstation for electro-optically reading targets in a reading field of view includes an object sensing system that senses an object entering the workstation by directing object sensing light through a window at the object, and detecting return object sensing light returned from the object along an object detection path through the window over an object detection field of view of an object light sensor. A portion of the object sensing light incident on the window is reflected therefrom into the object detection field of view as a virtual hot spot that degrades object sensor performance. An optical element, e.g., an aperture stop, in the object detection path optically modifies the object detection field of view to prevent the virtual hot spot from being detected by the object light sensor.
