摘要： Light is focused in a system for electro-optically scanning and reading bar code symbols by an aperture stop having a first optical portion (252) for optically modifying a first part of a light beam (262) to have a beam cross-section of a known size within a depth of field in which a symbol to be read is scanned by the first beam part, and a second light-transmissive, optical portion (254) bounding the first portion and operative for optically modifiying and directing a second part of the light beam (264) away from the first part.

摘要： A solid-state imager is mounted at a point-of-transaction workstation for capturing images of diverse targets useful for customer identification, customer payment validation, and operator surveillance. The imager is manually or automatically triggered and is operated at high speed to resist image blurring due to relative movement between the target and the imager.

摘要： A solid-state imager is mounted at a point-of-transaction workstation for capturing images of one- and two-dimensional indicia and is operated at high speed to resist image blurring due to relative movement between the target and the imager. Dedicated hardware assistance and computation resources are allocated to decode multiple, continuous and simultaneous video streams from multiple imagers at the workstation.

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.
