   Abstract : Sustainable wood nanotechnologies that combine optical transmittance and mechanical performance are interesting for new functionalities utilizing transparency. Wood is a sophisticated bio-based material with a natural hierarchical, anisotropic and porous structure. READ MORE

4. 22. Angle dependent light scattering of functional nanoparticle composites

   Author : JunXin Wang; Gunnar Niklasson; Anand Srinivason; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; light scattering; nano particle; absorption; radiative transfer; Solid State Physics; Fasta tillståndets fysik;

   Abstract : Varies functional nanoparticles play crucial roles in energy- and optical- related applications. The incorporation of functional nanoparticles into non-absorbing polymers to form optical absorption and scattering thin films have attracted considerable interest due to a successful selection of particles and matrices, synergistic effects of separation and fixation of particles, and controllable layer thicknesses and structures.

5. 23. Complex Oxide Photonic Crystals

   Author : Dzmitry Dzibrou; Alex Grishin; Peter Lazor; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photonic crystals; magneto-optical effects; refractive index; iron garnet; Optics; Optik;

   Abstract : Microphotonics has been offering a body of ideas to prospective applicationsin optics. Among those, the concept of photonic integrated circuits (PIC’s) has recently spurred a substantial excitement into the scientific community. Relisation of the PIC’s becomes feasible as the size shrinkage of the optical elements is accomplished. READ MORE

6. 24. Optical Characterisation of Miniature Structures and Translucent Sheets for Daylighting Applications

   Author : Jacob Jonsson; Arne Roos; Helen Rose-Wilson; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Photospectrometry; Light scattering; Optical characterisation; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Abstract : For a long time spectrophotometry has been a powerful method of determining optical material properties. Since the technique measures the parameters of interest, reflectance and transmittance, it is in general easy to use and interpret. READ MORE

7. 25. Assessment of optical coherence tomography for metrology applications in high-scattering ceramic materials

   Author : Rong Su; Lars Mattsson; Hjalmer Granberg; KTH; []
   Keywords : metrology; optical coherence tomography; alumina ceramics; nondestructive testing; imaging through turbid media; light scattering; image processing; numerical approximation and analysis; Monte Carlo method;

   Abstract : Large-scale and cost-effective manufacturing of ceramic micro devices based on tape stacking requires the development of inspection systems to perform high-resolution in-process quality control of embedded manufactured cavities, metal structures and defects.In this work, alumina ceramic samples are evaluated by optical coherence tomography (OCT) operating at 1.
