1. Phase-Contrast Imaging, Towards G2-less Grating Interferometry With Deep Silicon
University essay from KTH/FysikAbstract : Conventional phase-contrast imaging entails stepping an analyser grating across the detector to resolve the interference pattern caused by the x-rays after passing through a series of gratings in a so-called Talbot-Lau interferometer. However, the analyser grating in the interferometer poses a challenge, not only due to the machinery and alignment required but also due to each exposure delivering a dose to the subject. READ MORE

5. Periodic and Non-Periodic Filter Structures in Lasers
University essay from KTH/Matematik (Avd.)Abstract : Communication using fiber optics is an integral part of modern societies and one of the most important parts of this is the grating filter of a laser. In this report we introduce both the periodic and the non-periodic grating filter and discuss how there can be resonance in these structures. READ MORE
