  2. 1. Application and Design Developments in Diffractive Optics

    Author : Mathias Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analog-to-digital converter; free-space optical interconnect; beam shaper; robust fan-out; multichannel rotary joint; diffractive optics; DOE; subwavelength grating; spatial light modulator SLM ;

    Abstract : There has been strong development in the field of diffractive optics (DO) in research laboratories over the past two decades. Much progress has been made, both in design and analysis, as well as in manufacturing techniques. However, so far DO have only reached the market in small numbers. READ MORE

  6. 4. Spectroscopic techniques for photodynamic therapy dosimetry

    Author : Ann Johansson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; diffuse light spectroscopy; photodynamic therapy; biomedical optics; Atom- och molekylärfysik;

    Abstract : Photodynamic therapy (PDT) as a cancer treatment modality relies on the simultaneous presence of three components; light, photosensitiser and oxygen. Once excited by the light, the photosensitiser can interact with oxygen, leading to the formation of toxic oxygen species. READ MORE

  7. 5. Light Propagation and Gas Absorption Studies in Turbid Media Using Tunable Diode Llaser Techniques

    Author : Liang Mei; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gas in scattering media absorption spectroscopy; tunable diode laser absorption spectroscopy; frequency modulated light scattering interferometry; light propagation; Absorption spectroscopy; turbid media; diode laser; gas monitoring; porous media; ceramics; food packaging; Fysicumarkivet A:2014:Mei;

    Abstract : Optical absorption spectroscopy is a widely used analytical tool for constituent analysis in many applications. According to the Beer-Lambert law, the transmitted light intensity through a homogeneous medium is an exponential function of the product of the concentration, the total pathlength, and the absorption cross-section of the absorbing substance.
