  2. 2. Functional Textile Coatings Containing Flake-shaped Fillers investigations on selected optical and electrical properties

    University dissertation from Borås : Högskolan i Borås

    Author : Veronica Malm; Högskolan i Borås.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flakes; fillers; textile coating; properties; multilayered mica; effect pigment; angle-dependent colour change; metals; conductivity; resistance measurements; e-textiles; flexibility; durability; Textil och mode generell ; Textiles and Fashion General ;

    Abstract : This thesis investigates the manufacturing and characterisation of functionalised textile coatings containing different types of flake-shaped fillers with angle-dependent colour-changing and electrically conductive properties, respectively. Common benefits of these types of flakes are their high aspect ratio, which offers low filler loading with high functional performance. READ MORE

  4. 4. Cavity enhanced optical sensing

    University dissertation from Umeå : Umeå universitet

    Author : Isak Silander; Umeå universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optical resonators; Fiber Laser; Parametric oscillators; Optical frequency comb; Infrared; Spectroscopy heterodyne; Spectroscopy molecular; Absorption; Dispersion; Lineshapes; Optical standards and testing; Refractivety measurements;

    Abstract : An optical cavity comprises a set of mirrors between which light can be reflected a number of times. The selectivity and stability of optical cavities make them extremely useful as frequency references or discri­mi­nators. READ MORE

  5. 5. Optical Design for Stationary Solar Concentrators

    University dissertation from Faculty of Engineering, LTH at Lund University

    Author : Johan Nilsson; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photovoltaic cells; parabolic reflectors; optical efficiency; Solar concentrators; photovoltaic-thermal systems; non-imaging optics; optical properties; building integrated photovoltaics; non uniform irradiance distribution; structured reflectors; solar cell modelling; ray tracing;

    Abstract : Solar electricity is one of the most promising technologies for our future electricity supply. By using concentrators, it is possible to reduce the cost of generating photovoltaic electricity. This thesis discusses how to design stationary low concentrating systems for photovoltaic or PV/Thermal applications. READ MORE
