Abstract: A hand-supportable planar laser illumination and imaging (PLIIM) based camera system for producing digital linear images of a object within a working range, wherein the digital linear images contain pixels having a substantially uniform aspect-ratio independent of the measured relative velocity of the object while the PLIIM based camera system is manually moved (e.g. swept) past the object during illumination and imaging operations. The hand-supportable PLIIM based camera system comprises an object velocity measurement subsystem mounted within its hand-supportable housing, for determining the velocity of the object relative to the hand-supportable housing and generating object velocity data indicative of the determined velocity of the object. Also, a camera control computer is mounted within the hand-supportable housing, for controlling the operation of the PLIIM-based linear imaging subsystem, in automatic response to object velocity data generated by the object velocity measurement subsystem. During object illumination and imaging operations, the camera control computer (1) uses the object velocity data to determine a photo-integration time period parameter for the linear image detection array which produces digital linear images of the object, containing pixels having a substantially uniform aspect-ratio, independent of relative velocity of the object; and then (2) uses the determined photo-integration time period parameter to automatically control the operation of the linear image detection array so that the linear image detection array automatically produces digital linear images of the object, containing pixels having a substantially uniform aspect-ratio independent of the measured velocity of the moving object. By virtue of the present invention, it is now possible to produce digital images of objects containing pixels having a substantially uniform aspect-ratio, thereby satisfying the processing constraints associated with conventional 2-D bar code reading and OCR algorithms used in automatic object identification applications.

Abstract: 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.
