Publication number: 20240142683Abstract: The present disclosure relates to structured protective windows that have high transmission efficiency and can isolate light between different sections of the window. The structured protective windows are less prone to glass breakage compared to conventional protective windows that are typically used to protect and isolate light transmitting and light receiving components in LiDAR exterior automotive applications.Type: ApplicationFiled: March 24, 2022Publication date: May 2, 2024Applicants: SCHOTT Corporation, SCHOTT AGInventors: Oliver Sohr, Sebastian Leugner, Kevin Tabor, Elisabeth Han, Hauke Esemann

Publication number: 20240012197Abstract: The present disclosure relates to light isolating arrays (can also be called “light pipes” or “light pipe arrays”) that enable high transmission efficiency and isolation of light from one location, for example a lens, to another location, for example an array of photodetector diodes (each a “PD”). The light isolating arrays can provide optical isolation of the input light and can eliminate cross talk thus enhancing the resolution via increased contrast of the incoming signal. The light isolating arrays can also protect the PD's from contamination when used in outdoor devices.Type: ApplicationFiled: November 16, 2021Publication date: January 11, 2024Applicants: SCHOTT Corporation, SCHOTT AGInventors: Oliver Sohr, Sebastian Leugner, Kevin Tabor, Michael Dargie, Elisabeth Han

Publication number: 20210349258Abstract: An image-conducting optical fiber bundle extends along a central bundle axis between image input and image output ends. The bundle is twisted along a portion of its length such that an image inputted into the image input end is angularly displaced about the central bundle axis before being outputted through the image output end. Each constituent optical fiber includes a cladding with a cladding diameter corresponding with the fiber diameter of that fiber and a core with a core diameter. The ratio of the core diameter to the cladding diameter defines a core-to-clad diameter ratio relative to each fiber. In various embodiments, at least one of fiber diameter and core-to-clad diameter ratio varies as a function of a fiber's radial displacement from the central bundle axis.Type: ApplicationFiled: July 21, 2021Publication date: November 11, 2021Applicant: SCHOTT CorporationInventors: Kevin Tabor, Paige Higby, Paulette Onorato

Patent number: 8335419Abstract: An optical component includes at least one light-guiding element with a side surface extending between incident and emission faces between which light that is introduced into the incident face can propagate by internal reflection. Disposed over at least a portion of the side surface of at least one of the at least one light-guiding elements is an extramural absorption material that is configured to selectively absorb “stray light” that enters the incident face of the light-guiding element, but which exists through the side surface instead of the emission face. The absorption material is fabricated, at least in part, from an electro-chromic material exhibiting a translucency that is selectively adjustable in response to changes in at least one of (i) electrical current applied through at least a portion of the absorption material and (ii) an electrical potential difference applied between disparate locations within the absorption material.Type: GrantFiled: October 26, 2009Date of Patent: December 18, 2012Assignee: Schott CorporationInventor: Kevin Tabor

Publication number: 20110242272Abstract: A multi-directional imaging assembly includes a multi-directional imaging bundle having at least two rigid image-conducting branch elements. Each branch element has opposed image-input and image-output faces and at least one bend between the faces. The branch elements are mutually bound such that the image-input faces are disparately directed and the image-output faces coincide to define a common image-output face. Optically aligned with each image-input face is a focusing element that defines a field of view correlating to a spatial region. An image of the spatial region correlating to the field of view defined by a focusing element is acquired and projected onto the image-input face with which that focusing element is optically aligned. Images conducted through the branch elements, and outputted through the common image-output face, are optically communicated to an image detector array.Type: ApplicationFiled: February 18, 2011Publication date: October 6, 2011Inventors: Kevin Tabor, Scott A. Raszka, Kerry Highbarger

Patent number: 7856161Abstract: An imaging module includes an optical fiber faceplate with an image-input face, a planar image-output face, and a plurality of adjacently fused, internally reflecting imaging conduits extending between the image-input and image-output faces. The constituent imaging conduits extend along conduit axes that mutually converge in a direction that such that an image inputted through the image-input face is reduced in size along at least one dimension for outputting through the image-output face. The imaging module further includes an imaging detector array including a plurality of photosensitive detector elements arranged in accordance with a predetermined array format. The faceplate is situated in front of the detector array such that light incident upon the image-input face is transmitted through the faceplate and optically communicated to the detector elements through the image-output face. Multiple imaging modules can be tiled in tight formations in order to form a larger format imaging array.Type: GrantFiled: March 6, 2008Date of Patent: December 21, 2010Assignee: Schott CorporationInventor: Kevin Tabor

Publication number: 20090052850Abstract: Well plates adaptable for specimen sampling in the biological, chemical and pharmaceutical sciences are fabricated by dissolving fusedly-retained cores from the cladding material of a fused fiber plate to define a capillary plate including first and second faces and a plurality of through-voids into which fluidic samples may be deposited for analysis. Closed-bottom wells are defined by bonding one of the first and second faces to a base plate or by securing into well-sealing positions over the open ends of selected through-voids optical elements, each of which optical elements exhibits a predetermined optical property. Cladding material including reducible ions is exposed to a reducing atmosphere in order to blacken selected regions of a well plate, thereby enhancing sample analysis by reducing such disadvantageous phenomena as autofluorescence.Type: ApplicationFiled: October 1, 2007Publication date: February 26, 2009Inventors: Loic Barbedette, John Hansson, Richard Strack, Kevin Tabor, Michael Weisser

Patent number: 7400795Abstract: An elongated light-guiding element includes opposed incident and emission ends between which light propagates by total internal reflection. The light-guiding element includes a glass core with first and second glass core ends and a glass-core outer surface.
