Abstract: A method of generating a complex laser scanning pattern from a bioptical laser scanning system for providing 360° of omnidirectional bar code symbol scanning coverage at a point of sale station that employs a plurality of laser scanning stations about a two independently controlled rotating polygonal mirrors. The system has an ultra-compact construction, ideally suited for space-constrained retail scanning environments, and generates a 3-D omnidirectional laser scanning pattern between the bottom and side-scanning windows during system operation. The laser scanning pattern of the present invention comprises a complex of laser scanning planes, including a plurality of substantially-vertical laser scanning planes for reading bar code symbols having bar code elements (i.e. ladder type bar code symbols) that are oriented substantially horizontal with respect to the bottom-scanning window, and a plurality of substantially-horizontal laser scanning planes for reading bar code symbols having bar code elements (i.e. picket-fence type bar code symbols) that are oriented substantially vertical with respect to the bottom-scanning window.

Abstract: Embodiments of an indicia reading terminal have multiple fields of view (“FOV”). This feature allows decoding of decodable indicia that exhibit different characteristics. These characteristics may affect the ability of the terminal to identify and decode the information stored therein. In one embodiment, the terminal comprises an optical imaging assembly with at least two FOVs. One of the FOVs is adequate to acquire information from decodable indicia with higher density than other decodable indicia.

Abstract: A POS-based bar code symbol reading system that reads bar code symbols on objects being passed through the 3D imaging or scanning volume supported by the system, and employs one or more object motion sensors (e.g. imaging based, IR Pulse-Doppler LIDAR-based, ultra-sonic energy based, etc.) to (i) measure or estimate the speed of objects being manually passed through the 3D imaging or scanning volume by the system operator, and (ii) visually and/or audibly display object scanning speed measures or estimates to provide the system operator with feedback for optimizing system throughput. The POS-based bar code symbol reading system has a performance advantage that leads to quicker customer checkout times and productivity gain that cannot be matched by the conventional bar code symbol scanning technology.

Abstract: A laser illumination beam generation system including a laser diode (LD) for producing a laser beam in response to a diode current supplied thereto, wherein the laser beam has a central characteristic wavelength. Diode current drive circuitry generates the diode current and supplies the same to the VLD. A high frequency modulation (HFM) circuitry modulates the diode current supplied to the laser diode, so as to produce a spectral side-band components about the central characteristic wavelength, and thereby reduces the coherence of the laser illumination beam as well as its coherence length. An optical multiplexing (OMUX) device receives the laser beam as an input beam and generates multiple laser beams therefrom and recombines the multiple laser beams so as to produce a composite output laser illumination beam having reduce coherence.

Abstract: A method of driving a plurality of visible and invisible laser diodes so as to produce an illumination beam having a dynamically managed ratio of visible to invisible (IR) spectral energy/power during object illumination and imaging operations. The method involves supplying a plurality of visible laser and invisible laser diodes with a predetermined/default values of diode drive currents so as to illuminate the object with a spectral mixture of illumination during object illumination and imaging operations. One or more digital images of the illuminated object are captured and the image contrast quality thereof is measured, in real-time, so as to generate feedback or control data. This feedback or control data is used to dynamically generate the necessary values for the adjusted diode drive currents that are used to drive the visible and invisible laser diodes and produce an illumination beam having a dynamically managed ratio of visible to invisible (IR) spectral energy/power required to produce images of sufficient image contrast to ensure satisfactory image processing, while minimizing visual brightness to humans, at a POS station during object illumination and imaging operations.
