摘要： Methods of and systems for illuminating objects using planar laser illumination beams having substantially planar spatial distribution characteristics that extend through the field of view (FOV) of image formation and detection modules employed in such systems. Each planar laser illumination beam is produced from a planar laser illumination beam array (PLIA) comprising a plurality of planar laser illumination modules (PLIMs). Each PLIM comprises a visible laser diode (VLD), a focusing lens, and a cylindrical optical element arranged therewith. The individual planar laser illumination beam components produced from each PLIM are optically combined to produce a composite substantially planar illumination beam having substantially uniform power density characteristics over the entire spatial extend thereof and thus the working range of the system. Preferably, each planar laser illumination beam component is focused so that the minimum beam width thereof occurs at a point or plane which is the farthest or maximum object distance at which the system is designed to acquire images.

摘要： A fully automated package identification and measuring system, in which omni-directional laser scanning systems (10, 101, 107) are used to read bar codes on packages entering the tunnel, while a package dimensioning subsystem (600) is used to capture information about the package prior to entry into the tunnel. Mathematical models are created on a real-time basis for the geometry of the package and the position of the laser scanning beam used to read the bar code thereon. The mathematical models are analyzed to determine if collected and queued package identification data is spatially and/or temporally correlated with package measurement data using vector-based ray-tracing methods, homogeneous transformations, and object-oriented decision logic so as to enable simultaneous tracking of multiple packages being transported through the scanning tunnel.

摘要： Novel methods are disclosed for designing and constructing miniature optical systems and devices employing light diffractive optical elements (DOEs) for modifying the size and shape of laser beams produced from commercial-grade laser diodes, over an extended range hitherto unachievable using conventional techniques. The systems and devices of the present invention have uses in a wide range of applications, including laser scanning, optical-based information storage, medical and analytical instrumentation, and the like. In the illustrative embodiments, various techniques are disclosed for implementing the DOEs as holographic optical elements (HOEs), computer-generated holograms (CGHs), as well as other diffractive optical elements.

摘要： A modular omnidirectional laser-based bar code symbol scanning system having at least one scan module insert that is removably disposed within a system housing through a service port in the system housing. The scan module insert is a self-contained unit including at least the following components: at least one laser diode (11A1', 11A2'), a rotating scanning element (13A'), an electric motor (15A') that rotates the rotating scanning element, one or more photodetectors (17A1', 17A2'), and analog signal processing circuitry that conditions the electrical signal produced by the one or more photodetectors. The scan module insert can optionally include additional components including one or more light collecting , optical elements, one or more beam folding mirrors, circuitry for detecting and decoding bar code symbols scanned by the system, etc. The modular architecture of omnidirectional laser scanner of the present invention enables quick access to the scan module insert for efficient repair/reconfiguration/configuration of the optical components, electro-optical, electro-mechanical components and/or electrical components.
