Patent number: 10495491Abstract: This application relates to methods and apparatus for distributed fibre optic sensing, especially distributed acoustic sensing (DAS). The sensor apparatus (300) has an optical generator (303, 305, 306) for repeatedly generating a first coded sequence of optical radiation to be launched into a sensing optical fibre (302). The first coded sequence is encoded according to a polylevel coding sequence (101) and has desired autocorrelation properties. A detector (311) detects optical radiation which has been Rayleigh backscattered from within the sensing optical fibre and a processor (301c) processes the output of the detector. The processor processes the detector output in range bins and for each range bin correlating a detection signal derived from the detector output with the polylevel coding sequence at a time delay corresponding to that particular range bin.Type: GrantFiled: August 31, 2016Date of Patent: December 3, 2019Assignee: OPTASENSE HOLDINGS LIMITEDInventors: Andrew Lewis, Stuart Russell

Patent number: 10495568Abstract: An apparatus for analysing a sample of granular material, such as soil, is described. An elongated housing has a channel extending therethrough to define an optical path. A cavity is defined within the top of the housing to receive the sample, and a transparent sample-receiving surface is disposed within the cavity at a first elevation from the bottom of the housing. A lens assembly is positioned within the optical path at a second, lower, elevation. The lens assembly magnifies an image formed by light beams reflected by or transmitted through the sample. An image capturing device is disposed across the optical path at a third elevation that is lower than the second elevation. The image capturing device is thus lower than both the lens assembly and the transparent sample-receiving surface. A light source is mounted within the housing to emit light toward the sample-receiving surface.Type: GrantFiled: April 27, 2018Date of Patent: December 3, 2019Assignee: THE ROYAL INSTITUTION FOR THE ADVANCEMENT OF LEARNING/MCGILL UNIVERSITYInventors: Viacheslav Adamchuk, Asim Biswas, Long Qi, Maxime Leclerc, Bharath Sudarsan, Wenjun Ji

Patent number: 10451564Abstract: A method for qualitatively detecting aberration and determine aberration types in a photolithography system is disclosed. The method includes using a digital micromirror device (DMD) pattern to project an optical signal on a reflective substrate, acquiring a return optical signal reflected from the substrate at different focus heights (ranging from above to below best focus), forming a through focus curve based off of the return optical signal at various focus heights, comparing the through focus curve to a predetermined curve—the predetermined curve being a function of focus, and determining if a lens aberration is present. By using the existing hardware of the photolithography system to determine if a lens aberration exists, costs are maintained at a minimum and the DMD pattern creates a through focus curve (TFC) image in less than five minutes allowing for quick correction.Type: GrantFiled: April 25, 2018Date of Patent: October 22, 2019Assignee: APPLIED MATERIALS, INC.Inventors: Qin Zhong, Antoine P.
