Patent number: 10670622Abstract: The present invention relates to a displacement sensor device and the system including the device, wherein the device comprises a first at least partially transparent plane surface with a first diffraction pattern and a second plane surface comprising a second reflecting diffraction pattern. The diffractive patterns being adapted to diffract light within a chosen range of wavelengths, the second surface being positioned below and parallel to the first surface constituting a pair wherein said first and second diffractive patterns being essentially equal, the device also comprising displacement means for allowing a movement in a direction parallel to said surfaces, the device thus providing a movement sensitive diffraction pattern.Type: GrantFiled: January 18, 2019Date of Patent: June 2, 2020Assignee: PGS Geophysical ASInventors: Ib-Rune Johansen, Matthieu Lacolle, Thor Bakke, Andreas Vogl, Dag Thorstein Wang, Sverre Knudsen, Odd Løvhaugen, Hallvard Angelskår, Zeljko Skokic

Patent number: 7957004Abstract: This invention relates to an interference filter, especially for use in gas detection with infrared light within a chosen range, comprising at least two essentially parallel and partially reflective surfaces with a chosen distance between them thus defining a cavity delimited by the reflecting surfaces between which the light may oscillate, and wherein at least one of said surfaces is partially transparent for transmission of light to or from said cavity. The filter comprises a first transparent material having a high refractive index, e.g. silicon, positioned in at least a part of said cavity, and at least one of said reflective surfaces being divided into a three dimensional pattern with varying shift relative to its plane, thus to provide a position dependent resonance condition between them for separation of different wavelengths in the light.Type: GrantFiled: April 3, 2006Date of Patent: June 7, 2011Assignee: Sinvent ASInventors: Ib-Rune Johansen, Alain Ferber, Odd Løvhaugen, Håkon Sagberg

Patent number: 7701574Abstract: A diffractive optical element device for use in spectroscopy, where broadband light is emitted from a light source towards the optical element and from there is transmitted to at least one detector. The optical element has a plurality of diffractive dispersively focusing patterns, preferably partly integrated into each other, whose respective centers are two-dimensionally offset relative to each other in order to produce a plurality of spectra, where at least two are separate, but offset relative to each other and/or partly overlapping. In an alternative embodiment, the optical element consists of either one diffractive optical element that is related to a wavelength and produces a spectrum, or at least two diffractive optical elements which are related to respective wavelengths and which produce at least two mutually partly overlapping spectra to give a composite spectrum. The optical element is capable of producing at least one indication of upper and/or lower wavelength value in the spectrum.Type: GrantFiled: January 17, 2007Date of Patent: April 20, 2010Assignee: Tomra Systems ASAInventors: Ib-Rune Johansen, Odd Løvhaugen

Patent number: 7196791Abstract: A diffractive optical element device for use in spectroscopy, where broadband light is emitted from a light source (31) towards the optical element (24) and from there is transmitted to at least one detector (29; 29?). The optical element has a plurality of diffractive dispersively focusing patterns, preferably partly integrated into each other, whose respective centers are two-dimensionally offset relative to each other in order to produce a plurality of spectra (25–28), where at least two are separate, but offset relative to each other and/or partly overlapping. In an alternative embodiment, the optical element consists of either one diffractive optical element (60) that is related to a wavelength and produces a spectrum, or at least two diffractive optical elements (60, 61) which are related to respective wavelengths and which produce at least two mutually partly overlapping spectra to give a composite spectrum.Type: GrantFiled: November 30, 2001Date of Patent: March 27, 2007Assignee: Tomra Systems ASAInventors: Ib-Rune Johansen, Odd Løvhaugen
