High-resolution computed tomography with a compact soft x-ray microscopeMichael Bertilson
Department of Applied Physics, Royal Institute of Technology AlbaNova, Stockholm, Sweden
Opt Express 17:11057-65. 2009..Cryo-fixation, increased source brightness and extended-depth-of-focus objectives are important for pushing the resolution of compact systems for biological samples...
Sub-25-nm laboratory x-ray microscopy using a compound Fresnel zone plateOlov von Hofsten
Biomedical and X Ray Physics, Department of Applied Physics, Royal Institute of Technology, AlbaNova, SE 10691 Stockholm, Sweden
Opt Lett 34:2631-3. 2009..We analyze the illumination conditions necessary for this type of optics in order to suppress stray light and demonstrate microscopic imaging resolving 25 nm features...
Laboratory soft-x-ray microscope for cryotomography of biological specimensMichael Bertilson
Biomedical and X Ray Physics, Department of Applied Physics, KTH Royal Institute of Technology Albanova, 10691 Stockholm, Sweden
Opt Lett 36:2728-30. 2011..We demonstrate high-resolution imaging, as well as quantitative tomographic imaging, of frozen intact cells. The reconstructed tomogram of the intracellular local absorption coefficient shows details down to ∼100 nm...
Numerical model for tomographic image formation in transmission x-ray microscopyMichael Bertilson
Biomedical and X Ray Physics, Department of Applied Physics, KTH Royal Institute of Technology Albanova, Stockholm, Sweden
Opt Express 19:11578-83. 2011..Results show that both the depth-of-focus and the reconstructed local absorption coefficient are highly dependent on the degree of coherence of the optical system...
Theoretical development of a high-resolution differential-interference-contrast optic for x-ray microscopyOlov von Hofsten
Biomedical and X Ray Physics, Department of Applied Physics, Royal Institute of Technology AlbaNova, SE 10691 Stockholm, Sweden
Opt Express 16:1132-41. 2008..The optic is capable of a wavefront separation equal to the resolution of the optic which places only minor constraints on the object illumination...
