  6. 4. Nonlinear materials for optical power limiting : characterization and modelling

    Author : Hampus Lundén; Mikael Lindgren; Cesar Lopes; Bernd Eberle; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : High power laser pulses can be a threat to optical sensors, including the human eye. Traditionally this threat has been alleviated by colour filters that block radiation in chosen wavelength ranges. READ MORE

  7. 5. Optical Characterization and Optimization of Display Components : Some Applications to Liquid-Crystal-Based and Electrochromics-Based Devices

    Author : Iryna Valyukh; Claes-Göran Granqvist; Ewa Wäckelgård; Hans Arwin; Ola Hundery; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ellipsometry; liquid crystal; LCD; optical anizotropy; electrochromic; inverse problems; Optics; Optik; Optical physics; Optisk fysik; Numerical analysis; Numerisk analys; Solid State Physics; fasta tillståndets fysik; Information Systems; data- och systemvetenskap;

    Abstract : This dissertation is focused on theoretical and experimental studies of optical properties of materials and multilayer structures composing liquid crystal displays (LCDs) and electrochromic (EC) devices. By applying spectroscopic ellipsometry, we have determined the optical constants of thin films of electrochromic tungsten oxide (WOx) and nickel oxide (NiOy), the films’ thickness and roughness.
