  1. 1. Optical characterization of tissue for medical diagnostics

    University dissertation from Department of Physics, Lund University

    Author : Charlotta Eker; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tissue optical properties; tissue optics; near-infrared spectroscopy; multiple scattering; light propagation in tissues; fluorescence spectroscopy; optical mammography; in vivo diagnostics; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:1999:Eker;

    Abstract : This thesis deals with the development and evaluation of some different optical techniques for tissue characterization. The main aim has been to improve and evaluate such investigative techniques in in vivo studies. READ MORE

  2. 2. Optical Diagnostics of Non-thermal Plasmas and Plasma-assisted Combustion

    University dissertation from Lund Report on Combustion Physics

    Author : Jiajian Zhu; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; High-speed photography; Laser diagnostics; Planar laser-induced fluorescence; Plasma-assisted combustion; Non-thermal plasmas; Gliding arc discharge; Optical diagnostics; Particle tracking velocimetry; Fysicumarkivet A:2015:Zhu;

    Abstract : Non-thermal plasma is regarded as a collection of free electrons, ions and neutral particles that are not at local thermodynamic equilibrium. The high-energetic electrons formed in non-thermal plasmas are capable of generating chemically active species and modifying chemical kinetics in practical applications. READ MORE

  3. 3. Glaucoma Diagnostics

    University dissertation from Wiley-Blackwell

    Author : Sabina Andersson; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; POAG – glaucoma – diagnostic accuracy – screening – subjective assessment – population-based – GDx VCC – OCT – HRT – FDT – ONH assessment – CME – ANN – artificial neural network – visual field assessment;

    Abstract : This thesis addresses several aspects of glaucoma diagnostics from both a clinical and a screening perspective. New instruments for diagnosing glaucoma have been developed over the past years, but little information is available regarding their performance as screening methods and their usefulness in ordinary clinical practice.

  4. 4. Optical Diagnostics of Soot in Combusting Sprays

    University dissertation from Wiley-Blackwell

    Author : Raul Lima Ochoterena; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical diagnostics.; Laser Induced Incandescence LII ; Elastic Light Scattering ELS ; Soot formation; Flame temperature; Spray combustion; Light Extinction LE ;

    Abstract : Optical diagnostics in combusting diesel sprays were carried out in the Chalmers High Pressure, High Temperature (HP/HT) spray rig at conditions similar to those in an internal combustion engine, reaching up to 100 bar and 630 ◦ C. Spray development studies and combustion characterisation were done by high speed shadowgraphs that were digitally processed to measure the start of combustion, break-up, droplets and vapour penetration.

  5. 5. Laser diode systems for photodynamic therapy and medical diagnostics

    University dissertation from Department of Physics, Lund University

    Author : Eva Samsöe Andersen; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quasi-phasematching; photodynamic therapy; laser-induced fluorescence; medical laser systems.; Histology; cytochemistry; histochemistry; tissue culture; Histologi; Laserteknik; Laser technology; cytokemi; histokemi; vävnadskultur; Diagnostik; Diagnostics; second harmonic generation; pulsed lasers; spatial filtering; Diode lasers; optical feedback; Fysicumarkivet A:2004:Samsöe Andersen;

    Abstract : This work concerns techniques for improvement of the coherence properties of diode lasers so that they may be used in two specific medical applications: (Interstitial) photodynamic therapy (PDT) and laser-induced fluorescence diagnostics. In the first application, spatial coherence is crucial, since the treatment light should be delivered through relatively thin optical fibers to optimize treatment and to facilitate minimally invasive treatment.
