1. Improving image quality of a streak camera using periodic shadowing
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/FörbränningsfysikAbstract : Stray light suppression using a method inspired by lock-in amplification, called periodic shadowing, is examined and demonstrated for a measurement involving a streak camera. The experiment consists of resolving the fluorescent decay of the dye Rhodamine B (RhB) and examining both the rise and the decay of the fluorescence. READ MORE

4. Fiber-based Stray Light Suppression in Spectrometers
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/FörbränningsfysikAbstract : 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. READ MORE

5. Development of an Ultra-Sensitive Spectrometer
University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionenAbstract : A high dynamic range imaging (HDRI) spectroscopic instrument was designed and developed in this thesis. Achieving higher measurement accuracy in imaging spectroscopic measurements require both a suppression of the background light (stray light) as well as HDR imaging. READ MORE
