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: 7262380Abstract: A system for automatically inspecting matter for varying composition comprises one or more detection stations through which one or more streams of matter are advanced and particular materials therein are detected through their diffusely reflected IR spectra, if any, and/or through their variation of an electromagnetic field by their metallic portions, if any. A row of light sources distributed across the overall width of one or more belt conveyors may cause desired portions of the stream to reflect light diffusely onto a part-toroidal mirror extending over that overall width, whence the light is reflected, by a rotating, polygonal mirror through optical filters dedicated to differing IR wavelengths, onto detectors the data output of which is utilized in controlling solenoid valves operating air jet nozzles which separate-out the desired portions.Type: GrantFiled: April 3, 2000Date of Patent: August 28, 2007Assignee: Titech Visionsort ASInventors: Borre Bengt Ulrichsen, Clas Fredrik Mender, Geir Foss-Pedersen, Jon Henrik Tschudi, Ib-Rune Johansen
