摘要： An acousto-optical modulator modulates a green laser beam, and generates a modulated non-diffracted beam and a modulated diffracted beam. A scanner sweeps the modulated diffracted green beam, as well as modulated red and blue beams, as a pattern of scan lines, each scan line having a number of pixels. A controller causes selected pixels along the scan lines to be illuminated, and rendered visible, by the diffracted green beam, the red beam and the blue beam to produce the image. The non-diffracted green beam is employed in a laser shut-down safety circuit.

摘要： A plurality of image projection modules is operative for causing selected pixels in overlapping raster patterns to be illuminated to produce a large size image of high resolution of VGA quality in monochrome or color. The selected pixels in an overlap region of the patterns are illuminated at a lesser intensity to provide uniform brightness over the image. Multiple single mode lasers, or a multimode laser with an aperture stop, are employed to increase laser output power. Speckle noise is reduced by controlling the optical transmission characteristic of a projection screen. Three-dimensional images are generated by moving the screen. Cross-coupling between drive and feedback mechanisms in image projection is reduced for better image quality.

摘要： An illumination time of an illumination system and/or an exposure setting of an imaging system are adjusted by a proximity system operative for detecting a product entering a field of view in a bi-optical, dual window, point-of-transaction workstation. The proximity system includes an infrared emitter for emitting infrared light to the product, and an infrared sensor for sensing return infrared light from the product. Multiple predefined thresholds are stored for the sensed return infrared light, and a predefined illumination time and/or exposure setting are stored and assigned to each predefined threshold. Adjustment of the illumination time and/or of the exposure setting is performed by comparing the sensed return infrared light from the product in real time operation with the stored predefined thresholds.

摘要： Products associated with targets to be read by image capture are processed in a workstation having a window, a solid-state imager looking at a field of view extending through the window to a target to be imaged, and an illumination system for illuminating the field of view. A proximity system detects a product associated with the target in a selected zone outside the window. The proximity system has an infrared (IR) emitter for emitting IR light into an IR emission field, and an IR sensor for sensing return IR light within an IR detection field that intersects the IR emission field in the selected zone. A controller energizes the illumination system in response to the detection of the product in the selected zone, and processes return illumination light captured in the field of view by the imager.

摘要： A hand-held bar code reader, in particular a bar code wand is used by a consumer to read bar code information accompanying a product displayed at a retail outlet. The bar code information can be presented in, for example, UPC format and carries information relating to the products. The consumer subsequently down-loads information stored in the reader via a suitable interface to a personal computer which accesses information identified by a address included in or comprising the bar code information. The site contains additional information such as price information concerning the advertised product and the consumer may be able to pay for and order the product directly via the site. As a result the consumer has a simple reminder of the product, is able to obtain additional information concerning the product with minimum difficulty and can obtain the product itself with maximum ease.

摘要： An apparatus for, and method of, imaging printed and electronic codes associated with transactions or objects to be processed, support a window on a housing, illuminate the codes through the window with illumination light from an energizable illumination system, capture return illumination light from the illuminated codes through the window with an array of light sensors looking at a field of view of a solid-state, exposable imager, and process the captured return illumination light. A printed code is read by exposing the imager for a first exposure time and by also energizing the illumination system during the first exposure time. An electronic code is read by exposing the imager for a second exposure time that is longer than the first exposure time and by also deenergizing the illumination system during the second exposure time.
