    • All-chalcogenide variable infrared filter 

      Kondakcı, H. Esat; Köyle, Özlem; Yaman, Mecit; Dana, Aykutlu; Bayındır, Mehmet (SPIE, 2009)
      We present the design, fabrication, characterization of spatially variable infrared filter and a demonstration of the filter as a simple infrared spectrometer. A varying photonic band gap filter which consists of thermally ...

    • VOC gas leak detection using pyro-electric infrared sensors 

      Erden, Fatih; Soyer, E. B.; Toreyin, B. U.; Çetin, A. Enis (IEEE, 2010)
      In this paper, we propose a novel method for detecting and monitoring Volatile Organic Compounds (VOC) gas leaks by using a Pyro-electric (or Passive) Infrared (PIR) sensor whose spectral range intersects with the absorption ...
