摘要： A system and method is provided for illuminating a subject using a light pipe that transmits light from a source, such as an LED ring illuminator to an outlet that directs the light appropriately as either bright field illumination, dark field illumination or both. The light pipe can include concentric cylinders, typically with a bright field illuminator nested within a dark field illuminator. The tip of the dark field illuminator may be angled so as to internally reflect light inwardly toward the central optical axis of a camera at a low angle. The tip can be located near the focal plane of the camera for the desired field of view. The field of view of the camera sensor can be modified to reject data outside of a illumination field of a particular shape. This illumination field can be created by shaping the light pipe in a predetermined form that projects the modified illumination field. Likewise, a set of aiming illuminators (in, for example, a noticeable color) can be provided around the perimeter of the light pipe to delineate outer boundaries of the illumination field or area of interest. These approaches facilitate better aiming of the sensor into the desired area of interest so that it is illuminated and/or acquired most-fully.

摘要： A system and method is provided for selectively controlling the illumination, and particularly dark field illumination, applied to a symbol to be decoded, and for determining a suitable or optimized level of lighting for decoding the symbol. A ring-shaped illuminator is provided, and is segmented into a plurality of individually-controllable lighting portions which can be, for example, quadrants. Initially, illumination is provided to the symbol through an initial set of lighting conditions. Feedback from acquired image data is then used to determine whether the lighting is suitable for decoding the symbol and, if not, a controller varies the lighting applied to the symbol, and additional image data is acquired. This process is continued until suitable conditions are met. Alternatively, activation and deactivation of the lighting segments can be manually selected by an operator to provide suitable conditions.

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： This invention provides a field of view expander (FOVE) removably attached to a vision system camera having an image sensor defining an image plane. In an embodiment the FOVE includes first and second mirrors that transmit light from a scene in respective first and second partial fields of view along first and second optical axes. Third and fourth mirrors respectively receive reflected light from the first and second mirrors. The third and fourth mirrors reflect the received light onto the image plane in a first strip and a second strip adjacent to the first strip. The first and second optical axes are approximately parallel and a first focused optical path length between the scene and the image plane and a second focused optical path between the image plane and the scene are approximately equal in length. The optical path can be rotated at a right angle in embodiments.

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.

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： This provides a plurality of novel features that can be applied variously to a reader. In one embodiment, the light pipe is constructed from durable polycarbonate for increased shock resistance and can define a rectangular cross section. The chamfered end of the light pipe is textured or frosted to further diffuse refracted light passing through the end so as to present a more even effect. The conical/tapered diffuser within the light pipe is illuminated by a reflector with a white textured surface that reflects a plurality of rearward-directed illumination sources back into the diffuser. The reflector can define a predetermined cross section that directs further light into the forwardmost, remote regions of the diffuser to generate a better spread of light and alleviate spotting effects. The textured surface on the chamfered light pipe end can be employed to better project indicator light. The illumination sources are arranged in a ring at the inner end of the pipe, and can be multi-colored sources that respond to the controller to project and appropriate color and/or blink in an appropriate pattern to indicate various conditions, such as read success or failure. The controller is adapted to provide indications between image acquisitions. 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 (quadrants, for example) at a given time. Different quadrants may be simultaneously illuminated in different colors in one example
