1. Simulations and modeling of light propagation in biological tissue
University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska HögskolaAbstract : The GASMAS technique has previously proven useful for examining and measuring the oxygen concentration in the lungs of preterm infants. GASMAS can distinguish absorption by one gas from the bulk absorption of the surrounding media, and can provide an instant, non-invasive and non-destructive way of examining lungs, and diagnosing dangerous conditions such as pneumothorax.

2. Gas in Scattering Media Absorption Spectroscopy in Large Geometries: Towards Monitoring Oxygen in Adult Lungs
University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionenAbstract : GAs in Scattering Media Absorption Spectroscopy (GASMAS) is a technique to study free gas inside strongly scattering bulk-materials. GASMAS is successful in safely measuring oxygen in lungs of neonates, with low-power tuneable diode-laser spectroscopy at 760 nm. READ MORE

3. Weather Influence on LiDAR Signals using the Transient Radiative Transfer and LiDAR Equations
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : The ongoing development of self driving cars requires accurate measuring devices and the objective of this thesis was to investigate how di↵erent weather will affect one of these devices, known as a LiDAR. A LiDAR uses pulsed laser light to measure the distance to an object. READ MORE

4. Developing a technique for combining light and ultrasound for deep tissue imaging
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : Biological tissues are strongly light-scattering and absorbing media that limit the depth of optical-based imaging. Even though, optical imaging provides good optical contrast information of biological content that is beneficial for clinical diagnostics application. READ MORE

5. Optimization of measurement geometry for GASMAS lung function monitoring of infants
University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionenAbstract : A technique for measuring oxygen concentration in the lungs of preterm infants is one of the latest advancements in neonatal care. It is called GAs in Scattering Media Absorption Spectroscopy (GASMAS) and enables non-invasive, bed-side monitoring of the lung function of our most fragile patients, preterm newborns. READ MORE
