3. 2. Fiber-based Stray Light Suppression in Spectrometers

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Författare :Miaoxin Gong; [2017]
   Nyckelord :spectroscopy; spectrometer; stray light; fiber optics; Periodic Shadowing; lock-in analysis; Raman spectroscopy; Physics and Astronomy;

   Sammanfattning : Stray light is known as strong interference in spectroscopic measurements. With the creation of a novel kind of customized fibers, manufactured by the fiber optics group in Jena, Germany, a general experimental solution to this problem is possible. LÄS MER
