Abstract: An aiming system for use in a small height scan engine chassis. The aiming system includes a beam source assembly generating an input beam along a central axis and a collimator assembly having a lens group that defines a tilt axis having a tilt angle, ?, relative to the central axis, to deflect the input beam from the central axis onto the tilt axis. The collimator assembly further includes a recess within which a diffractive optical element is sealably mounted to convert the deflected input beam into an aiming pattern at a focal distance of the lens group.

An example optical assembly for a focusing lens includes: a front lens group disposed along an optical axis configured to receive light from the object of interest and configured to correct for aberrations of a first image projected by the front lens group; an aperture disposed along an optical axis configured to receive light from the front lens group therethrough along the optical axis; a moveable focus lens to receive light through the aperture; a VCM configured to move the focus lens to focus the optical assembly; and a back lens group disposed along the optical axis configured to receive light from the focus lens and further configured to correct for field curvature.

Abstract: A system and method for adaptively illuminating a volume with an illumination system that illuminates a volume of interest using separately controllable near field and far field optimized illumination sources, to maintain an irradiance pattern criteria in the volume, where that criteria may be different for a far field portion of the volume than for a near field portion of the volume.

Abstract: A system and method for illuminating a volume with an illumination system generating an illumination intensity pattern that maintains irradiance at sufficient on and off axis irradiance levels to allow for accurate identification and measure of objects within a volume, such as within a vehicle trailer or shipping container, is provided.

Abstract: A method and apparatus for capturing an image of at least one object appearing in a field of view (FOV). A housing has an image sensor and a base lens assembly fixedly mounted relative thereto. A moveable lens assembly is movably mounted relative to the housing. The moveable lens, the base lens assembly, and the image sensor are aligned such that light received within the FOV passes through the moveable lens and the base lens assembly and impinges onto the image sensor. The light received from the FOV forms an original image prior to entering the movable lens and the base assembly. Light from the FOV impinging onto the sensor forms an impinging image.

Abstract: Targets are read by image capture with a substantially constant resolution over an extended range of working distances. Return light returning from a far-out target located at a far-out working distance is sensed by an array of pixels over a relatively narrow field of view, and over a relatively wide field of view when a close-in target is located at a close-in working distance. A controller processes the sensed return light from the far-out target only from a set of the pixels located in a central region of the array. For the close-in target, the controller groups all the pixels into bins, each bin having a plurality of the pixels, and processes the sensed return light from the close-in target from each of the bins.

Abstract: A target to be read by image capture is illuminated with an illumination light pattern by an illuminating light assembly having an enhanced optical coupling efficiency. The assembly includes a hybrid lens component having a first lens portion centered on an optical axis, and a second total internal reflection (TIR) lens portion surrounding the first lens portion about the optical axis. Both lens portions intercept, bend and collimate illumination light emitted from a light emitting diode. The collimated light is incident on a lenslet component having an array of lenslets generally arranged in a plane that is generally perpendicular to the optical axis.

Abstract: An imaging scanner includes an aiming light source configured to emit visible light through both the shape defining element and the aiming lens arrangement to generate an aiming pattern on a target object. The shape of the aiming pattern changes with the distance between the target object and the imaging scanner. For determining the distance, the shape of the aiming pattern in a pixel data is compared with the expected shape of aiming patterns at multiple distances.

Abstract: Targets to be read by image capture are illuminated and imaged over an extended range of working distances. A near imager captures return light over a relatively wide imaging field of view from a target located in a close-in region of the range. A far imager captures return light over a relatively narrow imaging field of view from a target located in a far-out region of the range. A single illuminating light assembly is shared by both the near and far imagers. An illumination light source emits illumination light, and an illuminating lens assembly optically modifies the emitted illumination light, and simultaneously illuminates a wide illumination field to illuminate the target located in the close-in region of the range, and a narrow illumination field to illuminate the target located in the far-out region of the range.

Abstract: An apparatus includes (1) an imaging lens arrangement having an optical axis, (2) an aiming light source configured to project visible light through the imaging lens arrangement to create an aiming pattern on a target object, (3) an imaging sensor detecting light from the target object through the imaging lens arrangement, and (4) a folding mirror tilted relative to the optical axis of the imaging lens arrangement. The folding mirror is positioned both on the optical path from the imaging lens arrangement to the imaging sensor and on the optical path from the aiming light source to the imaging lens arrangement. Both the imaging arrangement and the aiming arrangement share the same imaging lens.

Abstract: An apparatus includes an illumination lens, an illumination light source for generating illumination light, and a prism made of optical transparent material. The first section on the first surface of the prism has a length that is at least four times as long as its width. The first surface of the prism includes a second section adjacent to the first section for defining the edge of an aperture. The third surface of the prism is configured to reflect the illumination light received from the first section onto the second surface of the prism. At least a portion of the illumination light received from the first section passes through both the second surface of the prism and the illumination lens for projecting illumination light onto a target object within an imaging field of view.

Abstract: The method of constructing a bi-optical workstation for imaging barcodes includes forming a window sheet by joining at least four rectangular-shaped sapphire sheets together with the area of the window sheet substantially equal to the sum of the areas of the at least four rectangular-shaped sapphire sheets. The method also includes constructing a first window on the housing with the first window located in a generally horizontal plane and constructing a second window on the housing with the second window located in a generally upright plane that intersects the generally horizontal plane. At least one of the first window and the second window comprises the window sheet formed by the at least four rectangular-shaped sapphire sheets.
