1. 6. Measuring the Optical Properties of Human Muscle Tissue using Time-of-Flight Spectroscopy in the Near Infrared

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Author : Staffan Strömblad; [2015]
   Keywords : photon; Time-of-Flight; muscle tissue; optical; spectra; Infrared; Physics and Astronomy; Technology and Engineering;

   Abstract : Optical spectroscopy is commonly used in technology and science today. The presence and concentration of a substance can be determined by its spectral signature, the typical wavelengths that are absorbed (or emitted) by the atoms or molecules. READ MORE

3. 7. Broadband Photon Time-of-Flight Spectroscopy on Pharmaceutical Tablets and Dairy Products

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Author : Sören Johansson; [2015]
   Keywords : Compositional Analysis; Dairy; Tablets; Pharmaceutics; Scattering; Absorption; Spectroscopy; Photonics; Optics; Chemometrics; Partial Least Squares; PLS; Physics and Astronomy;

   Abstract : In this thesis, Photon Time-of-Flight Spectroscopy (PTOFS) is presented as a method to measure absorption and scattering spectra of turbid media samples in the near infra red wavelength range. In particular, absorption and scattering spectra measured on pharmaceutical tablets and dairy products are used to analyse the composition of the samples. READ MORE

4. 8. Development of narrow-bandwidth filters for the suppression of scattered light for optical and ultrasound analysis of tissue

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Philip Dalsbecker; [2015]
   Keywords : biophotonics; Maxwell-Bloch equations; tissue; ultrasound; Ultrasound-modulated optical tomography; UOT; Physics and Astronomy;

   Abstract : Ultrasound-modulated optical tomography (UOT) is a proposed diagnostic technique with potential as a means of discovering cancerous tumours. The technique combines ultrasound and laser radiation to probe tissue in a non-invasive, harmless way. READ MORE

5. 9. Time of Flight Spectroscopy of Photon Migration in Turbid Media

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Author : Johanna Paulsson; [2014]
   Keywords : Physics and Astronomy;

   Abstract : Light interacting with biological matter is dominated by light scattering; biological matter is turbid. In order not to harm the natural structure of biological matter, visible light can be used to investigate it, and to avoid the light being absorbed from e.g. READ MORE

6. 10. Diffuse reflectance spectroscopy as a tool to evaluate liver tissue

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Atomfysik

   Author : Therese Alburg; David Kraus; [2014]
   Keywords : diffuse reflectance spectroscopy; drs; biophotonics; medical optics; diffusion; tissue evaluation; Technology and Engineering;

   Abstract : The shape of a diffuse reflectance spectra can provide knowledge about tissue composition. By analysing this spectra one can, with the right evaluation methods, find out information about the tissue. READ MORE
