    • Beyond the 2D limit: étendue-squeezing line-focus solar concentrators 

      Johnsen, Håkon Jarand Dugstad; Aksnes, Astrid; Torgersen, Jan (Peer reviewed; Journal article, 2020)
      Line-focus solar concentrators are commonly designed by extruding a two-dimensional concentrator in the third dimension. For concentration in air, these concentrators are, by the nature of their design, limited by the ...

    • Logistic splicing correction for VNIR–SWIR reflectance imaging spectroscopy 

      Grillini, Federico; Thomas, Jean-Baptiste Denis; George, Sony (Peer reviewed; Journal article, 2023)
      In the field of spectroscopy, a splicing correction is a process by which two spectra captured with different sensors in adjacent or overlapping electromagnetic spectrum ranges are smoothly connected. In our study, we ...

    • Micro-lensed optical fibers for a surface-enhanced Raman scattering sensing probe 

      Milenko, Karolina Barbara; Fuglerud, Silje Skeide; Kjeldby, Snorre B; Ellingsen, Reinold; Aksnes, Astrid; Hjelme, Dag Roar (Journal article; Peer reviewed, 2018)
      We present the fabrication and characterization of a novel sensing configuration based on surface-enhanced Raman scattering (SERS) and two micro-lensed optical fibers. The first micro-lensed fiber is used to excite surface ...
