摘要： This invention provides a system and method for expanding the field of view of a vision system camera assembly such that the field of view is generally free of loss of normal resolution across the entire expanded field. A field of view expander includes outer mirrors that receive light from different portions of a scene. The outer mirrors direct light to tilted inner mirrors of a beam splitter that directs the light aligned with a camera axis to avoid image distortion. The inner mirrors each direct the light from each outer mirror into a strip on the sensor, and the system searches features. The adjacent fields of view include overlap regions sized and arranged to ensure a centralized feature appears fully in at least one strip. Alternatively, a moving mirror changes position between acquired image frames so that a full width of the scene is imaged in successive frames.

摘要： An illumination system and method for use in a handheld symbology reader that employs a grid of reflecting elements applied to a transparent plate adapted to project a highly diffuse and uniform illumination on a subject. The grid defines a geometry with a large number of transparent spaces between grid elements through which an image of the subject can be acquired. A light source array is configured to project light into the grid at a right angle via a light pipe having a distal beveled edge or side projecting light sources. Another light source may be employed to illuminate second light pipe with a chamfered edge to create low-angle illumination.

摘要： A light transmitter (e.g., pipe) is constructed from polycarbonate for increased shock resistance and can define a rectangular cross section. A chamfered end of the light pipe is textured or frosted to further diffuse refracted light passing through the end to present a more even effect. A conical/tapered diffuser within the light pipe is illuminated by a reflector that reflects a plurality of rear-ward-directed illumination sources back into the diffuser. The reflector can direct light into the forwardmost, remote regions of the diffuser to generate a better spread of light and alleviate spotting effects. The illumination sources can be multi-colored sources that respond to a controller to project a color and/or blink in a pattern to indicate various conditions. The controller can operate individual portions of the ring so that only corresponding portions of the light pipe perimeter are illuminated in a particular color at a given time. Different quadrants may be simultaneously illuminated in different colors.

摘要： A method for scanning and decoding encoded symbols comprises processing low resolution image data from a full field of view and/or high resolution image data from one or more windowed segments of the field of view to provide imaging that is easily adaptable to different types of symbols and varying environmental conditions. The scanning method can be switched between the low resolution mode and the high resolution mode automatically based on whether the low resolution data is sufficiently accurate to decode the symbol.

摘要： Systems and methods provide an illumination assembly for a mark reader. A light transmitter is arranged in a surrounding relationship to an interior area, with the light transmitter having a proximal end and a distal end. An illumination source provides a light for transmission into the light transmitter. The light transmitter distal end allows the light from within the light transmitter to pass through and out of the distal end to provide bright field illumination and dark field illumination. The light transmitter distal end may include a first portion and a second portion, where light from within the light transmitter passes through and out of the first portion to provide bright field illumination, and light from within the light transmitter passes through and out of the second portion to provide dark field illumination.

摘要： A method and apparatus for indicating an in-focus or an out-of-focus condition for an imaging device (1, 2) in an optical reading and decoding apparatus (20) for receiving a coded image from a target area (29) on an article or package. In the method of the invention, two beams of light (27, 28) are generated to provide two illuminated aiming marks (32, 33) on the target. An in-focus condition is indicated when the two aiming marks are in a pre-defined spatial relationship relative to each other on the target. The in-focus condition or an out-of-focus condition can be signaled by controlling attributes of aiming marks (32, 33) or by controlling attributes of status indicator LEDs (12) on the apparatus (20) or by controlling an audible sound.
