1. Light propagation in an anisotropically scattering medium
Sammanfattning : Scattering is the main phenomenon of light-matter interaction. In this thesis, we consider one specific case of light propagation in a material whose structure causes anisotropic optical scattering - transparent wood. LÄS MER
2. Elastic wave scattering from corrugated surfaces in anisotropic media
Sammanfattning : .... LÄS MER
3. Multi-Scattering: Computational light transport in turbid media
Sammanfattning : This thesis presents and describes the development of an online freely accessible software called Multi-Scattering for the computational modeling of light propagation in scattering and absorbing media. The model is based on the use of the Monte Carlo method, where billions of photon packets are being launched and tracked through simulated cubic volumes. LÄS MER
4. Biomedical and atmospheric applications of optical spectroscopy in scattering media
Sammanfattning : Spectroscopic analysis of scattering media is difficult because the effective path length of the light is non-trivial to predict when photons are scattered many times. The main area of research for such conditions is biological tissues, which scatter light because of variations of the refractive index on the cellular level. LÄS MER
5. Laser Spectroscopy in Scattering Media for Biological and Medical Applications
Sammanfattning : Tunable diode laser absorption spectroscopy can be utilised for gas detection in biological and medical applications. The common approach is to analyse transmitted light according to the Beer-Lambertian law. LÄS MER
