  2. 1. Aspects of Optical Broad Band Spectroscopy and Information Extraction - Applications in Medicine and Ecology

    Author : Mikkel Brydegaard; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fluorescence Spectroscopy; Optical diagnostics; Electro-optics; Applied spectroscopy; Multispectral imaging; Optical spectroscopy; LIDAR; Remote sensing; Environmental monitoring; Chemometrics; Fysicumarkivet A:2012:Brydegaard Sörensen;

    Abstract : The present thesis describes a number of aspects of modern electro-optical measurement technology also known as bio-photonics; this includes instrumentation, applications, sample interaction and data interpretation. The methods employed operate over several domains, and light measurements are discretized both in intensity, space, angle, time, polarization and energy. READ MORE

  4. 2. Design, Fabrication and Analysis of InP-InGaAsP Traveling-Wave Electro-Absorption Modulators

    Author : Stefan Irmscher; KTH; []
    Keywords : fiber-optic communication; modulator; electroabsorption; traveling-wave; InP; broad-band modulation;

    Abstract : External modulators will become key components in fiberoptical communica- tion systems operating at 40Gbit/s andhigher bitrates. Semiconductor electro- absorption (EA)modulators are promising candidates because of their high-speed potential, and their process compatibility with thecorresponding semi- conductor laser light sources.

  5. 3. Adaptive Active Control of Machine-Tool Vibration in a Lathe - Analysis and Experiments

    Author : Lars Håkansson; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; Material technology; Metal Cutting; Lathe; Tool Vibration; Active Control; Adaptive Signal Processing; materialteknik;

    Abstract : In the turning operation the relative dynamic motion between cutting tool and workpiece, or vibration, is a frequent problem, which affects the result of the machining, and in particular, the surface finish. Tool life is also influenced by vibration. READ MORE

  6. 4. Optical Studies of Materials for Spectral Design

    Author : Christina Åkerlind; Kenneth Järrendahl; Hans Arwin; Hans Kariis; Isak Engquist; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Optical material properties have been studied in a wide wavelength range. Theaim is future use of spectral design for camou age. The main characterization techniques used in this work are Refection Spectroscopy, Scatterometry (BRDF) and Mueller Matrix Ellipsometry. READ MORE

  7. 5. Distant supernovae and galaxies in the Stockholm VIMOS Supernova Survey

    Author : Laia Mencia Trinchant; Göran Östlin; Duilia F de Mello; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; imaging surveys; photometric redshfits; Lyman Break galaxies; supernova typing; supernova rates; supernova host galaxies; Astronomy; Astronomi; Astronomy; astronomi;

    Abstract : Multi colour imaging surveys help astronomers to find galaxies and clusters,and to gain insights on their physical properties and evolution. In this thesis, I present the Stockholm VIMOS Supernova Survey (SVISS), where the ELAIS-S field was observed with VIMOS UBVRI broad-band optical bands over a period of 5 years. READ MORE
