    • A closer look at a spectrographic wavelength calibration 

      Henriksen, Marie Bøe; Sigernes, Fred; Johansen, Tor Arne (Peer reviewed; Journal article, 2022)
      Methods to spectrally calibrate imaging spectrographs, also known as Hyperspectral Imagers (HSIs), are common and known, but few look into how well the wavelength calibration performs. When building hyperspectral instruments ...

    • Comparing Filters for Correction of Second Order Diffraction Effects in Hyperspectral Imagers 

      Henriksen, Marie Bøe; Sigernes, Fred; Johansen, Tor Arne (Journal article; Peer reviewed, 2023)
      Second order diffraction effects often occur in hyperspectral instruments with dispersive elements. These second (and higher) order diffractions are typically unwanted, and should therefore be removed. One way of achieving ...

    • Comparing pre- and post-launch images from the HYPSO-1 cubesat hyperspectral imager 

      Henriksen, Marie Bøe; Garrett, Joseph; Johansen, Tor Arne; Sigernes, Fred (Journal article, 2022)
      HYPSO-1, a 6U cubesat carrying a hyperspectral imaging payload for ocean color observation, was launched in January 2022. During the commissioning and validation phases, the satellite and payload performance were tested. ...

    • Do it yourself hyperspectral imager for handheld to airborne operations 

      Sigernes, Fred; Syrjäsuo, Mikko; Storvold, Rune; Fortuna, João; Grøtte, Mariusz Eivind Santora; Johansen, Tor Arne (Journal article; Peer reviewed, 2018)
      This study describes rapid prototype construction of small and lightweight push broom Hyper Spectral Imagers (HSI). The dispersive element housings are printed by a thermoplastic 3D printer combined with S-mount optical ...

    • Do-it-yourself VIS/NIR pushbroom hyperspectral imager with C-mount optics 

      Henriksen, Marie Bøe; Prentice, Elizabeth Frances; van Hazendonk, Charlotte Maartje; Sigernes, Fred; Johansen, Tor Arne (Peer reviewed; Journal article, 2022)
      This paper describes a new optomechanical design based on a previously presented do-it-yourself pushbroom hyperspectral imager (HSI) using commercial off-the-shelf (COTS) components. The new design uses larger aperture ...

    • Hyperspectral Imager Calibration and Image Correction 

      Henriksen, Marie Bøe (Master thesis, 2019)
      Hyperspektrale kameraer, ombord blant annet droner og småsatellitter, skal detektere algeoppblomstring og andre havfenomener langs norskekysten. Dette er en del av prosjektet HYPSO, som står for "hyperspektral småsatellitt ...

    • HYPSO-1 CubeSat: First Images and In-Orbit Characterization 

      Bakken, Sivert; Henriksen, Marie Bøe; Birkeland, Roger; Langer, Dennis David; Oudijk, Adriënne Esmeralda; Berg, Simen; Pursley, Yeshi; Garrett, Joseph Landon; Gran-Jansen, Fredrik; Honoré-Livermore, Evelyn; Grøtte, Mariusz Eivind Santora; Kristiansen, Bjørn Andreas; Orlandic, Milica; Gader, Paul; Sørensen, Asgeir Johan; Sigernes, Fred; Johnsen, Geir; Johansen, Tor Arne (Peer reviewed; Journal article, 2023)
      The HYPSO-1 satellite, a 6U CubeSat carrying a hyperspectral imager, was launched on 13 January 2022, with the Goal of imaging ocean color in support of marine research. This article describes the development and current ...

    • On the calibration and optical performance of a Hyperspectral Imager for drones and small satellites 

      Henriksen, Marie Bøe (Doctoral theses at NTNU;2023:418, Doctoral thesis, 2023)
      English summary Hyperspectral Imagers (HSIs) are currently being developed for a range of applications. Among these are various forms of Earth observation from airborne platforms such as drones and small satellites. In ...

    • Pre-Launch Calibration of the HYPSO-1 Cubesat Hyperspectral Payload 

      Henriksen, Marie Bøe; Prentice, Elizabeth; Sigernes, Fred; Johansen, Tor Arne (Journal article; Peer reviewed, 2022)

    • Real-time Corrections for a Low-cost Hyperspectral Instrument 

      Henriksen, Marie Bøe; Garrett, Joseph; Prentice, Elizabeth Frances; Sigernes, Fred; Stahl, Annette; Johansen, Tor Arne (Journal article; Peer reviewed, 2019)
      The development of a hyperspectral imager (HSI) made from commercial off-the-shelf (COTS) parts enables the use of hyperspectral imaging on smaller low-cost platforms such as cubesats, drones, or other autonomous vehicles. ...
