    • An interferometric test station for massive parallel inspection of MEMS and MOEMS 

      Haugholt, Karl Henrik (Journal article; Peer reviewed, 2009)
      The paper presents the optical, mechanical, and electro-optical design of an interferometric inspection system for massive parallel inspection of Micro(Opto)ElectroMechanicalSystems (M(O)EMS). The basic idea is to adapt a ...

    • Automatic length estimation of free-swimming fish using an underwater 3D range-gated camera 

      Risholm, Petter; Mohammed, Ahmed Kedir; Kirkhus, Trine; Clausen, Sigmund; Vasilyev, Leonid; Folkedal, Ole; Johnsen, Øistein; Haugholt, Karl Henrik; Thielemann, Jens T (Peer reviewed; Journal article, 2022)
      Camera estimation of fish size in aquaculture production and fisheries is crucial for enabling knowledge-based decision making. Automatic estimation of fish lengths on an individual and population basis are key steps to ...

    • Design of a micro-optical low coherent interferometer array for the characterisation of MEMS and MOEMS 

      Gastinger, Kay; Haugholt, Karl Henrik; Røyset, Arne Karstein (Chapter, 2009)
      The EU-project SMARTIEHS (SMART InspEction system for High Speed and multi-functional testing of MEMS and MOEMS) develops a new inspection concept for MEMS and MOEMS (M(O)EMS) testing on the wafer level. The inspection ...

    • High-performance fixed-bed in situ mass analyzer - ISMA 

      Karlsson, Arne; Lødeng, Rune; Haugholt, Karl Henrik; Myhrvold, Elisabeth Meyer; Plassen, Martin (Peer reviewed; Journal article, 2023)
      We demonstrate a newly developed high-performance fixed-bed reactor combined with an in situ mass analyzer (ISMA). The ISMA is particularly relevant to sub-second time-resolved studies where mass changes occur due to, e.g., ...

    • Optical, mechanical and electro-optical design of an interferometric test station for massive parallel inspection of MEMS and MOEMS 

      Haugholt, Karl Henrik (Chapter, 2009)
      The paper presents the optical, mechanical, and electro-optical design of an interferometric inspection system for massive parallel inspection of MicroElectroMechanicalSystems (MEMS) and MicroOptoElectroMechanicalSystems ...

    • Range-Gated Imaging System for Underwater Monitoring in Ocean Environment 

      Mariani, Patrizio; Quincoces, Inaki; Haugholt, Karl Henrik; Chardard, Yves; Visser, André W.; Yates, Chris; Piccino, Giuliano; Reali, Giancarlo; Risholm, Petter; Thielemann, Jens T (Journal article; Peer reviewed, 2018)
      High-quality video observations are very much needed in underwater environments for the monitoring of several ecosystem indicators and to support the sustainable development and management of almost all activities in the ...

    • Real-time super-resolved 3D in turbid water using a fast range-gated CMOS camera 

      Risholm, Petter; Thorstensen, Jostein Bruun; Thielemann, Jens T; Kaspersen, Kristin; Tschudi, Jon; Yates, Chris; Softley, Chris; Abrosimov, Igor; Alexander, Jonathan; Haugholt, Karl Henrik (Journal article; Peer reviewed, 2018)
      We present a range-gated camera system designed for real-time (10 Hz) 3D estimation underwater. The system uses a fast-shutter CMOS sensor (1280×1024 1280×1024 ) customized to facilitate gating with 1.67 ns (18.8 cm in ...
