• Fabrication of an array of silicon microscales for the monitoring of chemical processes 

      Lacolle, Matthieu Jean P; Johansen, Ib-Rune; Wang, Dag Thorstein; Moe, Sigurd T.; Sagberg, Håkon; Clausen, Sigmund; Karlsson, Arne; Akporiaye, Duncan (Journal article; Peer reviewed, 2012)
      We present the fabrication and demonstration of a two-dimensional array of scales micromachined in silicon. Each scale consists of a platform suspended by a spring. The mass present on the platform of each scale is measured ...
    • Optical MEMS filter for infrared gas detection 

      Bakke, Thor; Lacolle, Matthieu Jean P; Sagberg, Håkon; Johansen, Ib-Rune; Moe, Sigurd T. (Lecture, 2008)
      An optical filter is proposed, which can be adapted to infrared detection of various gases. The filter is based on a diffraction grating structured on a micro-electro-mechanical system (MEMS) which can be switched between ...
    • Two-state Optical Filter Based on Micromechanical Diffractive Elements 

      Sagberg, Håkon; Bakke, Thor; Johansen, Ib-Rune; Lacolle, Matthieu Jean P; Moe, Sigurd T. (Chapter, 2007)
      We have designed a robust two-state filter for infrared gas measurement, where the filter transmittance alternates between a single bandpass function, and a double-band offset reference. The device consists of fixed and ...
    • Wood's anomalies and spectral uniformity of focusing diffractive optical elements 

      Angelskår, Hallvard; Johansen, Ib-Rune; Lacolle, Matthieu Jean P; Sudbø, Aasmund Sveinung (Journal article, 2010)
      We report on simulations and measurements of focusing diffractive optical elements, fabricated as two-level binary optics. The diffractive optical elements are designed to separate and focus four specific wavelengths in ...
