Abstract: An optical code reader of the imager type is disclosed, having an illumination lens (15) associated with a light source. In a first direction (X), a main face (16) of the lens (15) has a plurality of elementary regions (17), each having a slope with respect to an optical axis (A-A) of the reader that is individually calculated so that said elementary region (17) deviates the light fraction coming from the light source and incident thereon towards a specific elementary region of an illumination pattern. It is thus possible to create any desired irradiance profile.

Abstract: A hand held industrial identification symbol reader projects diffuse illumination onto a region of interest to produce high contrast images of symbols. The diffuse illumi­nation is particularly well suited for producing images of symbols that are marked di­rectly on objects. The diffuse illumination is created through the use of an optically trans­lucent diffuser having a generally tapered shape that distributes diffuse illumination throughout the field of view of the reader. The diffuse illumination can be supplemented with dark field illumination using selectively actuated illumination sources.

Abstract: Diffuse "dark field" illumination (90) and "bright field" illumination (162, 164) are each provided for a hand-held encoded symbology imager/reader; to be projected therefrom upon symbology disposed on a target (component part, goods, package, etc.). The imager/reader (30) is encased in a housing ergonomically configured to be gripped in more than one manner and to thus facilitate holding the imager/reader steady. The symbology to be imaged (40, 42, 44) is targeted by a line that not only spots the symbology, but by extending a length commensurate with that of the symbology, indicates that the symbology is in the field of view of the imager/reader. A CCD (252), disposed to receive light reflected from the symbology, has its readout controlled so that only selected portions of the CCD need to be analyzed for illumination and focusing purposes. To optimize imaging and decoding time, and to optimize use of power, readout from some portions of the CCD is accomplished in relatively rapid time by speeding up the readout of the CCD in some of its active area; while reverting back to a slower readout for data to be analyzed for illumination and focusing control and decoding purposes. In addition, special application of entropy principles facilitate determining the optimum focus and illumination conditions for the imager/reader.

Abstract: A hand held label reader (10) is capable of illuminating a label (20), capturing a digital image of two-dimensional information indicia (15) on the label, and decoding the digital image to provide decoded output data to a terminal (35). The target label is illuminated by a low variation illuminator that includes a circular LED array mounted behind a plano-convave dispersing lens. The automatic electronic camera, which includes a CCD camera and control circuitry, uses three images to adjust the intensity of the digital image and store a properly exposed image of the label in video RAM. The intensity of the digital image is adjusted by controlling the video system gain via adjusting the CCD array's integration time, the gain of a video amplifier, and the gain provided by an analog-to-digital converter. The gain provided by the analog-digital-converter is adjusted to compensate for the attenuation of light through the camera's lens assembly. For the first image, the digital image is obtained using a default setting for the gain. The image intensity is analyzed using a histogram process and new gain settings are determined. The second image is obtained using the gain settings derived from the first image. The second image intentity is analyzed and the gain settings are adjusted. These settings are used for the third video image. The digital image from the third image is stored in video RAM, where it is available to be decoded by a microprocessor.

Abstract: Indicia are imaged at a workstation having windows arranged in intersecting planes. The workstation also has solid-state imagers with fields of view that are split into intersecting subfields.that look out through the windows, as well as illumination assemblies each having multiple light sources that illuminate each subfield with illumination light over an illumination field that overlaps a respective subfield. Light-modifying elements, such as lenses or baffles that are radially offset from the multiple light sources, condition the illumination light from the multiple light sources to be generally uniform in light intensity over at least one illuminated subfield.

Abstract: A hand held, omnidirectional symbology or bar code reader (10) images linear and two-dimensional bar codes (28; 34; 40; 52; 54) over relatively long working distances. The reader (10) includes an imaging system including a focusing objective taking lens (92) and a two-dimensional photodetector (93) that forms an image of a bar code in X and Y directions simultaneously and generates an electrical signal representative of the code for subsequent downstream processing. Focusing is achieved via a rotating disk (94) that carries a plurality of optical shims (130) or other light controlling surfaces for different focus zones. A through-the-lens (TTL) targeting system is provided to visually assist the user in positioning the reader (10) for a variety of code modalities to assure that a bar code will be captured within the field of view and be sharply imaged on the photodetector (93) when the lens (92) is focused. Two different forms of artificial illumination are provided to accommodate nearby codes that may be either specular or partially diffuse and more distant codes where the reflection characteristics have less impact on code contrast. All of the reader's components are housed in an ergonomically designed shell (12) to reduce user repetitive stress injuries while providing access to a user interface and a protective cover for the reader's various systems.
