摘要： A hand-supportable planar linear illumination and imaging (PLIIM) based code symbol reading system comprising: a hand-supportable housing having a light transmission aperture; and a planar laser illumination and imaging module (PLIIM), disposed in the hand-supportable housing. The PLIIM includes (i) a linear image detection array having optics providing a field of view (FOV) on said linear image detection array that projects through the light transmission aperture, and (ii) at least one planar laser illumination module (PLIM) for producing a substantially planar laser illumination beam (PLIB) that extends substantially along the same plane as the FOV of the linear image detection array. This arrangement provides a coplanar illumination and imaging plane that projects through the light transmission aperture, for capturing a series of linear (1-D) digital images of an object intersecting therewith during object illumination and imaging operations. An image frame grabber then accesses 1-D digital images therefrom and composes a 2-D digital image of the object. An image data buffer buffers 2-D images received from the image frame grabber, and a decode image processor processes the digital images stored within the image data buffer so as to read one or more code symbols graphically represented in the digital images. A system controller controls the operations within the system.

摘要： An imaging engine includes a plurality of linear imaging arrays, image formation optics, at least one illumination module and supporting circuitry that are embodied within a modular engine housing. The plurality of linear imaging arrays and image formation optics are mounted on an optical bench (which is integral to the engine housing) and provide field of views corresponding to the plurality of linear image arrays. The at least one illumination module produces planar light illumination that substantially overlaps the field of views corresponding to the plurality of linear imaging arrays. The supporting circuitry includes: timing signal generation circuitry that supplies timing signals to the linear imaging arrays in order to read out the row image data produced by such arrays (such row image data may be read out at a constant line rate or at a variable line rate); illumination control circuitry that supplies current to the illumination sources in the at least one illumination module; analog-to-digital conversion circuitry, which optionally filters row data image signal supplied thereto (to remove unwanted noise components) and converts the row image data supplied thereto into digital form; and data buffering circuitry, for storing the digital row image data generated by the analog-to-digital conversion circuitry and communicating the row image data stored therein over a data communication bus. One linear image array (e.g., linear imaging array C) may have a variable line rate that is controlled by the timing signals supplied thereto such that the image capture operations performed by the one linear imaging array (e.g. linear imaging array C) maintain a substantially constant aspect ratio, to thereby compensate for aspect ratio distortions that result from variations in velocity of engine with respect to target object(s). The variable line rate is based upon velocity estimates derived from processing of the pixel data values of other linear imaging arrays disposed therein. The supporting circuitry may optionally include a line rate adjustment module, preferably realized as part of a programmed controller, that is operably coupled to timing signal generation circuitry and adjusts the variable line rate of the one linear image device (e.g., linear imaging array C); output illumination control module, preferably realized as part of the programmed controller, that is operably coupled to the illumination control circuitry and adjusts the optical power level and/or illumination time period for the illumination that overlaps one or more of the FOVs of the linear imaging arrays of the engine for speckle reduction/constant white levels; and/or imaging processing circuitry, operably coupled to the data buffering circuitry over the data communication bus, that realizes portions of image-based mechanisms/techniques for image velocity estimation, aspect ratio compensation, jitter estimation and compensation, bar code detection, OCR, and image lift.

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 an 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 laser 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, thereby compensating for decreases in the power density of the incident planar laser illumination beam due to the fact that the width of the planar laser illumination beam increases in length for increasing object distances away from the imaging optics. By virtue of the present invention, it is now possible to use both VLDs and high-speed CCD-type image detectors in conveyor, hand-held and hold-under type scanning applications alike, enjoying the advantages and benefits that each such technology has to offer, while avoiding the shortcomings and drawbacks hitherto associated therewith.
