Abstract: At least some embodiments of the present invention are directed toward optical arrangements for use in providing illumination light emitted by a barcode reader. In some embodiments, the arrangement includes an illumination source, a lens positioned within the path of the illumination light emitted by the illumination source where the lens is operable to collimate the light and redirect its central axis, and a window positioned within the path of the redirected and collimated light where the window is operable to alter the illumination light such that the resulting illumination light beam has a height-to-width ratio of less than 8 to 25.

Abstract: A modular off-platter detection assembly for use with a barcode reader includes a housing, a first light source, a first light sensor, and a controller operatively coupled to the first light source and the first light sensor. The housing is configured to be removably mounted to the barcode reader, a frame supporting the barcode reader, or the workstation. The first light source is positioned within the housing and emits a first light along a first lateral edge of a weigh platter. The first light sensor is positioned within the housing, has a first field-of-view along the first lateral edge, and is configured to detect at least a portion of the first light reflected towards the housing. The controller is configured to provide a first alert in response to receipt of a first value from the first light sensor indicating there is an object extending across the first lateral edge.

Abstract: A method and apparatus for directing an aim light through a window of an image reader. The window has a cylindrically curved section. The aim light impinges on a portion of the cylindrically curved section of the window prior to partially passing through the window. A first amount of the aim light is passed through the window, and a second amount of the aim light is reflected into the cavity resulting in reflected aim light. The reflected aim light is directed away from the imaging assembly such that no or substantially no reflected aim light impinges on the imager of the imaging assembly.

Abstract: In an embodiment, the present invention is a barcode reader that includes: a first imaging assembly configured to capture a first image; a second imaging assembly positioned relative to the first imaging assembly and configured to capture a second image; and a controller communicatively coupled to the first imaging assembly and the second imaging assembly. The controller is configured to: calculate a first contrast level within a first region within the first image; calculate a second contrast level within a second region within the second image; execute a first barcode-decode operation on the first image when the first contrast level is greater than the second contrast level; and execute the first barcode-decode operation on the second image when the second contrast level is greater than the first contrast level.

Abstract: A scan engine for capturing at least one image of an object appearing in an imaging field of view (FOV) is provided that includes an imaging system, illumination system, aiming system, and a first and second chassis. The imaging system includes a lens holder and at least one lens disposed within the lens holder and both a far imaging system and a near imaging system for capturing images across multiple fields of view at different distances. The illumination system and aiming system are physically positioned to provide illumination of a target in the near and/or far fields of view, and provide an aiming pattern to the near and/or far fields of view.

Abstract: An imaging assembly for capturing at least one object appearing in a field of view (FOV) is provided that includes an image capturing system, a controller operatively coupled to the image capturing system to control operation thereof, and a processor operatively coupled to the controller. The image capturing system is adapted to capture an image having at least one sub-frame and is further adapted to obtain distance information of the object. The processor analyzes the image to determine a brightness value of at least a portion of the image and analyzes the distance information of the object to determine a distance value from the imaging assembly to the object. The processor further determines an illumination characteristic based on the brightness value and the distance value.
