Patent number: 9373017Abstract: A scanning system has a collimated light source and a movable reflective surface. The surface receives light from the light source, reflects the received light to a target surface, receives light reflected from the target surface, and reflects this light to a detector. An aperture disposed between the reflective surface and the target surface has a non-transmissive portion with a width in a direction perpendicular to the laser scan direction that varies over the scan direction.Type: GrantFiled: April 26, 2013Date of Patent: June 21, 2016Assignee: Datalogic Automation, Inc.Inventors: Xinping Liu, Edward I Chaleff

Patent number: 9088683Abstract: A system for scanning objects having at least two linear array sensors, adapted to detect light input signals, is provided. A lens is optically connected to each of the linear array sensors, and are adapted to receive and transmit an optical image located in a respective lens field of view along a respective lens axis to the respective one of the at least two linear array sensor. A light source which generates an illumination stripe in general linear alignment with the lens axis across a depth of the field of view is provided. A cylindrical lens is positioned between the light source and an object to be scanned. The cylindrical lens adapted to collect, transmit and focus light from the light source to form the illumination stripe. This arrangement provides a wider system field of view with generally more uniform resolution.Type: GrantFiled: July 22, 2011Date of Patent: July 21, 2015Assignee: DATALOGIC AUTOMATION, INC.Inventors: Edward I. Chaleff, Thomas J. Brobst, Richard J. Skokowski, Jr.

Patent number: 6053409Abstract: A focus changing apparatus for an optical scanner which increases the depth of the field of the optical scanner. The focus changing apparatus is optically located between a laser source and a scan mirror and includes a plurality of alternating curved and flat facets. Alternatively, a piezoelectric deformable mirror may be optically located between the laser source and a flat faceted scan mirror to provide for increased depth of field of the optical scanner.Type: GrantFiled: June 24, 1997Date of Patent: April 25, 2000Assignee: Accu-Sort Systems, Inc.Inventors: Thomas J.
