Patent number: 9253393Abstract: An imaging system having a solid-state auto focusing system advantageously images broadband light reflected from an object to be imaged using a lens objective having chromatic aberration, which focuses different colors of light at different focal planes. Using the color information in the focal planes in conjunction with an object distance determined by a range finder, a luminance plane is constructed that has a focused image of the object. The system provides the focused image of the object without the use of any moving parts.Type: GrantFiled: March 9, 2015Date of Patent: February 2, 2016Assignee: Intermec IP, Corp.Inventors: Alain Gillet, Serge Thuries

Publication number: 20160026838Abstract: A scanner system is operable for gathering graphic data from a scan target. The scanner system has a single illumination source component operable for generating light, for aiming the scanner system with a filtered beam of the generated light directed at the scan target, and for illuminating the scan target with the directed light. The scanner system also has a detector component operable for sensing a reflection from the scan target, the sensed reflection including a portion of the directed light with which the scan target is illuminated, and for detecting information in the sensed reflection, in which the information detected in sensed reflection corresponds to the graphic data gathered from the scan target.Type: ApplicationFiled: October 13, 2015Publication date: January 28, 2016Inventors: Alain Gillet, Serge Thuries

Patent number: 9234782Abstract: Volume dimensioning employs techniques to reduce multipath reflection or return of illumination, and hence distortion. Volume dimensioning for any given target object includes a sequence of one or more illuminations and respective detections of returned illumination. A sequence typically includes illumination with at least one initial spatial illumination pattern and with one or more refined spatial illumination patterns. Refined spatial illumination patterns are generated based on previous illumination in order to reduce distortion. The number of refined spatial illumination patterns in a sequence may be fixed, or may vary based on results of prior illumination(s) in the sequence. Refined spatial illumination patterns may avoid illuminating background areas that contribute to distortion. Sometimes, illumination with the initial spatial illumination pattern may produce sufficiently acceptable results, and refined spatial illumination patterns in the sequence omitted.Type: GrantFiled: September 26, 2014Date of Patent: January 12, 2016Assignee: Intermec IP CorporationInventors: Franck Laffargue, Alain Gillet, Serge Thuries

Patent number: 9224022Abstract: An autofocus lens system includes no conventional moving parts and has excellent speed and low power consumption. The system includes a small electronically-controlled focusing-module lens. The focusing-module lens includes two adjustable polymeric surfaces (e.g., two adjustable-surface lenses in a back-to-back configuration). The curvature of the surfaces can be adjusted to change focus. The performance of the autofocus lens system is extended by adding a conventional first and second lens, or lens group, on either side of the focusing-module lens. What results is an autofocus lens system with excellent near field and far field performance.Type: GrantFiled: April 29, 2014Date of Patent: December 29, 2015Assignee: Hand Held Products, Inc.Inventors: H. Sprague Ackley, Alain Gillet

Patent number: 9158953Abstract: A reader obtains image data corresponding to an image of optically encoded information that is received via a lens unit that causes controlled spherical aberration blurring that is precisely known. The reader may perform deconvolution processing on the image data to render it decodable. The deconvolution processing may implement a Weiner filter that uses data corresponding to a near-field point spread function of the lens unit. The depth of field of the reader is greater than that of conventional reader in all lighting conditions.Type: GrantFiled: February 14, 2014Date of Patent: October 13, 2015Assignee: Intermec Technologies CorproationInventors: Alain Gillet, Vincent Bessettes

Publication number: 20150053769Abstract: Machine-readable symbol readers and/or scan engines may subtractively impose an aiming pattern on an illumination field produced by a source of light or illumination. An optical component with a mask or filter are interposed in an optical path extending outwardly from the source of light or illumination. The mask or filter may have a defined shape or configuration to subtractively produce an aiming pattern with a desired shape or configuration. The mask or filter may, or may not, be wavelength selective or spectral. A wavelength selective mask or filter may produce an aiming pattern of a defined color, different from a color of an illumination field. Such may eliminate the need for a separate, distinct source of light or illumination for an aiming beam subsystem. The described structures and methods may reduce size, reduce parts count, and/or simplify manufacture.Type: ApplicationFiled: August 21, 2014Publication date: February 26, 2015Inventors: Serge Thuries, Alain Gillet

Patent number: 8556179Abstract: A 2D bar code reader with improved motion tolerance is presented. The 2D bar code reader includes a lens configuration that enhances chromatic aberration to separate the focal planes on which bar code images from two different color components of a light will be focused. An imager interprets one of the focal planes as the image and the other one as noise to be ignored. In addition, the increased depth of field generated by the chromatic aberration allows for a larger aperture stop setting and quicker shutter speed, thereby improving motion tolerance.Type: GrantFiled: August 16, 2011Date of Patent: October 15, 2013Assignee: Intermec IP Corp.Inventors: Alain Gillet, Serge Thuries
