Patent number: 9411180Abstract: An apparatus and method for determining and quantifying “sparkle”—the random noise that is generated when a pixelated image is viewed through a roughened surface of a transparent sample. The apparatus includes a pixelated source and an imaging system located in an optical path originating from the pixelated source, wherein a transparent sample may be placed in the optical path between the pixelated source and the optical system. The degree of sparkle is determined by obtaining an integrated image for the pixelated image; and calculating a standard deviation of the integrated pixel power. An objective level of sparkle can be defined by correlating the amount of sparkle provided by the apparatus with visual impressions.Type: GrantFiled: January 20, 2012Date of Patent: August 9, 2016Assignee: CORNING INCORPORATEDInventors: Jacques Gollier, Shandon Dee Hart, Garrett Andrew Piech, James Andrew West

Publication number: 20150331149Abstract: A distortion-reducing anti-glare (DRAG) structure is disclosed, wherein the DRAG structure includes first and second transparent mediums. The first transparent medium has a first refractive index and a first light-scattering anti-glare (AG) surface. The first AG surface by itself reduces glare but introduces an amount of distortion to the transmitted light. A second transparent medium having a second refractive index greater than the first refractive index is selectively added to the first transparent medium to reduce the amount of distortion in the transmitted light.Type: ApplicationFiled: May 31, 2013Publication date: November 19, 2015Applicant: CORNING INCORPORATEDInventors: Dana Craig Bookbinder, Shandon Dee Hart, Karl William Koch, James Andrew West

Publication number: 20110249695Abstract: Concepts of the present disclosure may be employed to optimize optical pumping and ensure high modal gain in the active region of an optically pumped laser source by establishing an optical coupling gap such that the pump waveguide mode field overlaps the active gain region associated with the signal waveguide. The optical coupling gap is tailored to be sufficiently large to ensure that a significant active gain region length is required for absorption and sufficiently small to ensure that the pump waveguide mode field P overlaps the active gain region. In accordance with one embodiment of the present disclosure, the pump waveguide core is displaced from the signal waveguide core by an optical coupling gap g in a lateral direction that is approximately perpendicular to the optical pumping axis.Type: ApplicationFiled: April 13, 2010Publication date: October 13, 2011Inventors: Dmitri Vladislavovich Kuksenkov, Dmitry Sizov, James Andrew West

Patent number: 7428360Abstract: An optical waveguide environmental sensor is provided that is capable of detecting a target gas or liquid in the ambient environment in an advantageously short period of time. The waveguide is preferably in the form of an optical fiber having a cladding that contains a photonic band gap structure which in turn envelopes a light conducting, hollow core portion. The cladding further includes at least one elongated side opening that preferably extends the entire length of the fiber and exposes said hollow core portion to the ambient environment, which provides broad and nearly immediate access of the core portion to gases and liquids in the ambient environment, thereby minimizing sensor response time. The ambient gases or liquids filling the hollow core portion and elongated opening function as a ridge and slab, respectively, of an optical ridge waveguide that effectively supports at least one bound optical mode.Type: GrantFiled: January 14, 2008Date of Patent: September 23, 2008Assignee: Corning IncorporatedInventors: Michael Thomas Gallagher, Karl William Koch, III, Ellen Marie Kosik Williams, James Andrew West
