• 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 ...
    • 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 ...
    • 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. ...
