    • Design tool for TOF and SL based 3D cameras 

      Bouquet, Grégory; Thorstensen, Jostein Bruun; Bakke, Kari Anne Hestnes; Risholm, Petter (Journal article; Peer reviewed, 2017)
      Active illumination 3D imaging systems based on Time-of-flight (TOF) and Structured Light (SL) projection are in rapid development, and are constantly finding new areas of application. In this paper, we present a theoretical ...

    • High-quality dense 3D point clouds with active stereo and a miniaturizable interferometric pattern projector 

      Thorstensen, Jostein Bruun; Thielemann, Jens T; Risholm, Petter; Gjessing, Jo; Dahl-Hansen, Runar Plunnecke; Tschudi, Jon (Peer reviewed; Journal article, 2021)
      We have built and characterized a compact, simple and flexible 3D camera based on interferometric fringe projection and stereo reconstruction. The camera uses multi-frame active stereo as basis for 3D reconstruction, ...

    • Study of waveguide background at visible wavelengths for on-chip nanoscopy 

      Coucheron, David Andre; HELLE, OYSTEIN I.; Wilkinson, James S.; MURUGAN, GANAPATHY SENTHIL; DOMINGUEZ, CARLOS; Angelskår, Hallvard; AHLUWALIA, BALPREET S. (Peer reviewed; Journal article, 2021)
      On-chip super-resolution optical microscopy is an emerging field relying on waveguide excitation with visible light. Here, we investigate two commonly used high-refractive index waveguide platforms, tantalum pentoxide ...

    • Towards high-throughput large-area metalens fabrication using UV-nanoimprint lithography and Bosch deep reactive ion etching 

      Dirdal, Christopher Andrew; Jensen, Geir Uri; Angelskår, Hallvard; Thrane, Paul Conrad Vaagen; Gjessing, Jo; Ordnung, Daniel Alfred (Peer reviewed; Journal article, 2020)
      We demonstrate the fabrication of diffraction-limited dielectric metasurface lenses for NIR by the use of standard industrial high-throughput silicon processing techniques: UV nano imprint lithography (UV-NIL) combined ...
