- Nonintrusive gas monitoring in neonatal lungs using diode laser spectroscopy: feasibility studyMärta Lewander
Lund University, Division of Atomic Physics, P O Box 118, SE 221 00 Lund, Sweden
J Biomed Opt 16:127002. 2011..Our work suggests that the technique could provide a new possibility for surveillance of the lung function of preterm infants, in particular the oxygenation, which is of prime importance in this patient group...
- Clinical system for non-invasive in situ monitoring of gases in the human paranasal sinusesMärta Lewander
Department of Physics, Lund University, Sweden
Opt Express 17:10849-63. 2009..In addition, we discuss the use of water vapor as a reference in quantification of in situ oxygen concentration in detail. In particular, light propagation aspects are investigated by employing photon time-of-flight spectroscopy...
- Simultaneous detection of molecular oxygen and water vapor in the tissue optical window using tunable diode laser spectroscopyLinda Persson
Atomic Physics Division, Lund University, Lund, Sweden
Appl Opt 47:2028-34. 2008..The power of the technique is illustrated by the preliminary results of a clinical trial, nonintrusively investigating gas in human sinuses...
- Laser absorption spectroscopy of water vapor confined in nanoporous alumina: wall collision line broadening and gas diffusion dynamicsTomas Svensson
Division of Atomic Physics, Department of Physics, Lund University PO Box 118, SE 221 00 Lund, Sweden
Opt Express 18:16460-73. 2010..9 GHz for free molecules (atmospheric pressure). Gas diffusion is also investigated, and in contrast to molecular oxygen (that moves rapidly in and out of the alumina), the exchange of water vapor is found very slow...
- Non-invasive diagnostics of the maxillary and frontal sinuses based on diode laser gas spectroscopyMärta Lewander
Division of Atomic Physics, Department of Physics, Lund University, Lund, Sweden
Rhinology 50:26-32. 2012..This situation is largely due to a lack of reliable and widely applicable diagnostic methods...
- Disordered, strongly scattering porous materials as miniature multipass gas cellsTomas Svensson
Department of Physics, Lund University, Box 118, SE 221 00 Lund, Sweden
Phys Rev Lett 107:143901. 2011..Path length enhancement factors up to 750 are reached (5.4 m path through gas for light transmitted through a 7 mm ZrO(2) with 49% porosity and 115 nm pores)...
