Patent number: 8289603Abstract: Optical pattern generators use rotating reflective axicon segments to produce images that can have different dimensions along the pattern direction compared to the cross pattern direction. Examples include both single axicon pattern generators and dual axicon pattern generators that independently control the image space relative aperture and thereby control the image dimensions in two orthogonal directions.Type: GrantFiled: December 11, 2008Date of Patent: October 16, 2012Assignee: Reliant Technologies, Inc.Inventors: Leonard C. DeBenedictis, David A. Dewey, George Frangineas, Barry G. Broome

Patent number: 7995259Abstract: An optical pattern generator uses a rotating component that includes a number of deflection sectors containing optical elements. Each sector deflects an incident optical beam by a substantially constant angle although this angle may vary from one sector to the next. The constant deflection angle is achieved by symmetry within the deflection sector, specifically gut-ray symmetry. The rotating component may be combined with an imaging group that produces, for example, image points, spots, or lines displaced along a line locus. The image spots can also be displaced to either side of a line, for example by introducing a tilt in the orthogonal direction or by introducing light beams at various angles to the plane of symmetry.Type: GrantFiled: May 21, 2008Date of Patent: August 9, 2011Assignee: Reliant Technologies, Inc.Inventors: Barry G. Broome, Thomas R. Myers, Leonard C. DeBenedictis, David A. Dewey

Patent number: 7729029Abstract: An optical scan engine includes a rotatable component, for example a disk or drum. The rotatable component includes a plurality of scan sectors that are arranged around the rotation axis and that lie substantially in a plane of rotation. Each scan sector includes a pair of reflective surfaces that typically are radially-facing. The incident optical beam typically propagates along a radial direction (e.g., towards the rotation axis) and each pair of reflective surfaces deflects the incident optical beam by approximately 180 degrees as that pair rotates through the incident optical beam. The deflected optical beam has a virtual image located on the rotation axis. As a result, the real image of the deflected optical beam rotates around the rotation axis at the same angular velocity as the scan sectors. Different scan sectors can be designed to yield diffeent deflections in the axial direction.Type: GrantFiled: May 1, 2008Date of Patent: June 1, 2010Assignee: Reliant Technologies, Inc.Inventor: Barry G. Broome

Patent number: 6297913Abstract: A compact zoom lens system having four injection-molded singlet lens elements is described. In one embodiment, the compact zoom lens system includes a lens carrier and first and second lens elements coupled to the lens carrier. One surface of the first or second lens elements having a diffractive optical surface disposed thereon to correct chromatic aberrations of light passing therethrough. The lens carrier moves the first and second lens elements axially to change a focal length of the lens system. Third and fourth lens elements are fixed on either side of the first and second lens elements. The lens carrier includes an aperture stop placed proximate to the diffractive optical surface to correct chromatic aberrations over an entire range of focal lengths. The first lens element is made out of flint-like material while the other lens elements are made out of crown-like material. Moreover, the zoom lens system includes an anti-aliasing surface on one of the lens elements to control aliasing effects.Type: GrantFiled: June 19, 2000Date of Patent: October 2, 2001Assignee: Intel CorporationInventors: David M.

Patent number: 6292312Abstract: Several embodiment of an athermalizing apparatus is described. In one embodiment, the athermalizing apparatus includes a lens element and a support member coupled to the lens element. The support member has a sloped outer surface and a first coefficient of thermal expansion (“CTE”). The athermalizing apparatus further includes a rib member having a substantially complementary sloped surface that bears on the sloped outer surface of the support member. The rib member has a second CTE. The sloped outer surface of the support member forms a ramp angle with respect to an optical axis of the lens element. A radial expansion of the support and/or rib member causes an axial displacement of the support member as a function of the ramp angle.Type: GrantFiled: April 27, 2000Date of Patent: September 18, 2001Assignee: Intel CorporationInventor: Barry G.

Patent number: RE40329Abstract: An optical disk reader or read/write system for CD or DVD formats. First and second laser diodes operating at different wavelengths have their output beams collimated and directed at a single element objective lens, and are then reflected off the disk back through the lens to a photodetector. The single element objective lens has a central aperture zone and an outer aperture zone, the central zone being profiled to operate at a first numerical aperture at approximately 0.45 and the output beam of the first laser diode is confined to the central aperture zone. The outer aperture zone together with the central aperture zone are profiled to operate at a second numerical aperture, for example 0.60 wherein the output beam of the second laser diode has ray fans extending across the full aperture of the single element objective lens.Type: GrantFiled: July 5, 2002Date of Patent: May 20, 2008Assignee: Konica CorporationInventors: Barry G.
