    Abstract : Eta Carinae is one of the most massive and luminous stars in the Galaxy. A huge bipolar nebula and an equatorial disk give the object a characteristic shape. Close to the star there are gas clouds, which emit intriguing emission line spectra. READ MORE

  7. 5. Diffuse Optical Spectroscopy and Imaging of Turbid Media

    Author : Can Xu; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; upconverting nanoparticles; luminescence; fluorescence; inverse problem; diffuse reflection spectroscopy; biomedical optics; photon migration; biomedical imaging; gas spectroscopy; medical diagnostics; tomography; Fysicumarkivet A:2013:Xu;

    Abstract : This thesis deals with optical spectroscopy and imaging of complex and strongly scattering turbid media. Focus is mainly placed on three topics, being i) diffuse optical spectroscopy of choroidal tumors, ii) gas spectroscopy in scattering materials using the GASMAS (gas in scattering media absorption spectroscopy) technique, and iii) luminescence diffuse optical imaging and tomography of tissues.
