Abstract: An optical assembly for an autofocus imaging system for capturing at least one image of an object appearing in an imaging field of view (FOV) is provided. The optical assembly includes a front aperture along an optical axis and a front lens group along the optical axis that receives light from the object of interest. The position of the front lens group is adjustable to change a focal distance of the optical assembly. The optical assembly further includes an actuator physically coupled to the front lens group that adjusts the position of the front lens. A rear lens group is disposed along the optical axis to receive the light from the front lens group, and an imaging sensor is disposed at a back focal distance of the rear lens group, to detect the light.

Abstract: A method and system for controlling illumination according to eye safety standards. The method includes a processor retrieving from a memory of an illumination module, device information indicative of properties of the illumination module. The device information includes a plurality of parameters of an illumination element of the illumination module, and a maximum constant for the illumination element. The maximum constant is associated with a desired eye safety standard and is also indicative of a relationship between at least two parameters of the illumination element. The method further includes receiving, from a user, a desired parameter value for one of the parameters of the plurality of parameters. The processor determines a test constant from the desired parameter value, and the processor compares the test constant and maximum constant to determine if the desired parameter value is an acceptable value.

Abstract: Methods and devices for performing color imaging processing on the fly for barcode readers are disclosed herein. An example method includes color image processing in a barcode reader to identify one of raw image data or processed image data and further decoding indicia in the identified raw or processed image data. The method includes receiving a raw image data of an image of an object, performing image processing on the raw image data, analyzing the raw image data and the processed image data, and identifying which of the raw image data or processed image data to communicate to a decoder for further decoding. The decoder then identifies, in the identified raw image data or processed image data, indicia corresponding to an object, and decodes the identified indicia.

Abstract: Machine vision devices with configurable illumination and aiming pattern generation are disclosed. An example system includes a housing having a cavity; an imaging sub-assembly mounted in the cavity including: an imager configured to capture an image; an aiming light source mounted in the housing configured to generate a collimated beam of light, an illumination light source configured to generate illumination light; and interchangeable first and second cover plates configured for mounting to the housing in front of the imaging sub-assembly to form an external cover for the housing and sealably protect the imager from an environment, wherein the first and second cover plates have respective passive optical elements that modify the collimated beam of light to form respective aiming patterns, and wherein at least one of the first cover plate or the second cover plate has a third optical element that modifies the illumination light.

Abstract: A method and apparatus for capturing an image of at least one object appearing in a wide-angle field of view (FOV). A housing has an image sensor and a lens assembly fixedly mounted relative thereto. The lens assembly includes first and second lens groups, and a glass lens. The lens assembly and the image sensor are aligned such that light received within the FOV passes through a front aperture 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 front aperture and the lens assembly. Light from the FOV impinging onto the sensor forms an impinging image.

Abstract: An apparatus for capturing an image of at least one object appearing in an imaging field of view (FOV). A housing has an imaging sensor operably coupled with the circuit board, the imaging sensor configured to capture an image frame appearing in the imaging FOV and defining an imaging axis. An illumination assembly has a plurality of light sources operably coupled with the circuit board, a diffuser positioned adjacent to the plurality of light sources, the diffuser configured to generate a diffused light pattern, and a light pipe positioned adjacent to the plurality of light sources to generate a direct illumination pattern and an off-axis illumination pattern, wherein the direct illumination pattern is oriented generally parallel to the imaging axis and the off-axis illumination pattern is configured to intersect the imaging axis.

Abstract: Systems and methods for user choice of barcode scanning ranges are provided. This is achieved through the identification of a predetermined pixel-per-module threshold range. The pixel-per-module of a barcode being read by a reader is compared to the predetermined pixel-per-module threshold range, and a successful decode of the barcode is carried out only if the pixel-per-module of the barcode falls within the predetermined range. Thus, a user may select a desired reading distance range such that barcodes within a working distance range may not generate successful decodes if such barcodes are outside of the desired reading distance range.
