摘要： An image capture system for, and a method of, reading an optical code during a reading mode, comprise an aiming assembly including a laser for emitting a laser beam having a variable intensity, and for generating an aiming pattern from the laser beam during an aiming mode prior to the reading mode, and an imager for detecting and capturing an image of the aiming pattern and the code over a field of view by exposure over an exposure time period during the aiming mode, and for detecting and capturing an image of the code over the field of view during the reading mode. A controller is operative for controlling the intensity of the laser beam during the aiming mode by increasing the intensity of the laser beam during the exposure time period to enhance detection and capture of the aiming pattern by the imager, and by decreasing the intensity of the laser beam frame outside the exposure time period for user safety.

摘要： Barcode fragments of a barcode symbol to be read by an imaging-based presentation workstation are stitched together by capturing a plurality of images, each containing a barcode fragment and a plurality of features located adjacent to the barcode fragment. The features in each captured image are detected and matched. The barcode fragments are stitched together based on the matched features in the captured images. The barcode symbol is read from the stitched barcode fragments.

摘要： Laser power monitoring arrangements interrupt power to a laser used in electro-optical readers upon detection of operating conditions not conforming to preestablished standards. An auxiliary light detector independently monitors the output power of a laser beam, and directly receives a portion of the laser beam reflected from an optical assembly operative for optically modifying the laser beam.

摘要： The combination of a rooftop optical element and a soft edge aperture stop, as well as the introduction of a negative spherical aberration in a positive focusing lens, improve working distance and depth of focus in both moving beam and imaging readers for electro-optically reading indicia such as bar code symbols, especially for close-in symbols, and moreover tend to reduce undesirable light intensity modulation in the beam profile thereby improving reader performance.
