   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Brillouin light scattering; optics; spinwave spectroscopy; phonon spectroscopy; microscopy; Fabry-Perot interferometer; Frequency comb;

   Sammanfattning : Brillouin light scattering (BLS), an almost a century-old technique, has evolved into a powerful and versatile method to study acoustic and magnetic phenomena down to the nanometer size scale. Presently, BLS can be applied in fields as diverse as acoustics, spintronics, geosciences, and biophysics. LÄS MER

   Sammanfattning : Soft x-ray microscopy in the water-window (λ = 2.28 nm – 4.36 nm) is based on zone-plate optics and allows high-resolution imaging of, e.g. LÄS MER

5. 4. Development of Nonlinear Microscopy for Studies of Metabolism and Tissue Engineering

   Författare :Madeleine Åkeson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; imaging; bacterial cellulose; nonlinear microscopy; Saccharomyces cerevisiae; yeast; C. elegans; Microscopy; lipid storage;

   Sammanfattning : Nonlinear microscopy techniques provide abilities for noninvasive and selective imaging of structural and chemical properties of biological systems. These techniques include coherent anti-Stokes Raman scattering (CARS) microscopy with the ability to selectively image molecular vibrations, second harmonic generation (SHG) microscopy which selectively images fiber structures, and third harmonic generation (THG) microscopy which is sensitive to interfaces between materials with different optical properties.

7. 5. Phase-Contrast and High-Resolution Optics for X-Ray Microscopy

   Författare :Olof von Hofsten; Ulrich Vogt; Ian McNulty; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microscopy; X-ray optics; X-ray microscopy; Soft X-ray physics; Optics; Optik; Physics; Fysik;

   Sammanfattning : X-ray microscopy is a well-established technique for nanoscale imaging. Zone plates are used as microscope objectives and provide high resolution, approaching 10 nm, currently limited by fabrication issues. This Thesis presents zone plate optics that achieve either high resolution or phase contrast in x-ray microscopy. LÄS MER
