Sigernes F, Syrjasuo M, Storvold R, Fortuna J, Grotte M, Johansen T
Opt Express . 2018 Mar; 26(5):6021-6035. PMID: 29529798
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...

Sigernes F, Ivanov Y, Chernouss S, Trondsen T, Roldugin A, Fedorenko Y, et al.
Opt Express . 2012 Dec; 20(25):27650-60. PMID: 23262713
A prototype auroral hyperspectral all-sky camera has been constructed and tested. It uses electro-optical tunable filters to image the night sky as a function of wavelength throughout the visible spectrum...

Volent Z, Johnsen G, Sigernes F
Appl Opt . 2009 Jul; 48(21):4170-6. PMID: 19623231
In the presented study a hyperspectral imager (400-700 nm) mounted on a stereo-microscope was used to separate differences in in vivo optical signatures identifying different pigment groups of bloom-forming phytoplankton...
