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.

摘要： A hand-supportable linear-type planar laser illumination and imaging (PLIIM) based device comprising a linear image formation and detection (IFD) module having a linear array of image detection elements and also image formation optics having a field of view (FOV) focusing a linear image of an object onto the linear array of image detection elements. A pair of planar laser illumination arrays (PLIAs) is arranged on opposite sides of the linear image formation and detection module, and produces a plurality of spatially-incoherent planar laser illumination beam (PLIB) components that are optically combined with respect to other PLIB components so as to produce a composite planar laser illumination beam (PLIB) that is arranged in a coplanar relationship with at least a portion of the FOV. Each PLIA includes a plurality of planar laser illumination modules (PLIMs). Each PLIM includes a laser diode and beam focusing and diverging optics for producing one spatially-incoherent PLIB component. The composite PLIB produces a number of substantially different individual speckle noise patterns at the linear array of image detection elements during the photo-integration time period thereof. The speckle noise power observed at the linear array of image detection elements is reduced through temporal averaging of the individual speckle noise patterns during the photo-integration time period. By virtue of the present invention, it is now possible to use visible laser diodes (VLDs) to produce speckle-reduced images of objects suitable for OCR processing, while enjoying improved working distances offered by planar laser illumination techniques.

摘要： A method of extending the working distance of a planar laser illumination and imaging system without increasing the output power of the visible laser diode (VLD) sources employed therein. The method comprises the steps of: providing a planar laser illumination and imaging system having (1) a plurality of planar laser illumination modules (PLIMs) for producing a planar laser illumination beam, and (2) an image formation and detection (IFD) subsystem having a field of view along which the planar laser illumination beam extends, wherein each PLIM has a visible laser diode (VLD) source and beam focusing optics and beam planarizing optics, and the IFD subsystem has image formation optics for determining the maximum working distance of the system; adjusting the imaging optics of the IFD subsystem from an original working distance of the system to an extended working distance thereof; and adjusting the beam focusing optics so that the planar laser illumination beam is focused at the extended working distance.
