6. Optical Methods for Tympanic Membrane Characterisation : Towards Objective Otoscopy in Otitis Media
Sammanfattning : Otitis media, which is an upper respiratory tract infection that affect the middle ear, is the second most common disease in childhood, outnumbered in prevalence only by the common cold. Diagnosis of middle ear inflammation is often performed in the primary healthcare where the normal procedure involves anamnesis and physical examination of the tympanic membranes (TM) of the patient, usually be means of otoscopy.

7. Optical Design for Stationary Solar Concentrators
Sammanfattning : Solar electricity is one of the most promising technologies for our future electricity supply. By using concentrators, it is possible to reduce the cost of generating photovoltaic electricity. This thesis discusses how to design stationary low concentrating systems for photovoltaic or PV/Thermal applications. LÄS MER
8. Optical Measurements of Rolling Friction Coefficients
Sammanfattning : This thesis presents an optical method to measure the rolling friction coefficientsfor balls rolling freely on a cylindrical surface. Two different models of a ball rollingfreely on a cylindrical surface are established, one is an analytical model and the otheris a numerical model derived from Lagrange equation. LÄS MER
9. ORMOCER Materials Characterization, LAP- & Micro-Processing : Applied to Optical Interconnects and High-Frequency Packaging
Sammanfattning : ORMOCERR®s are organic-inorganic hybrid polymers. Since their material properties can be tailored precisely during synthesis, they are suitable for a wide range of applications in dielectric and optical microelectronics. LÄS MER
10. In Vivo Diffuse Reflectance Spectroscopy of Human Tissue : From Point Measurements to Imaging
Sammanfattning : This thesis presents the non-invasive use of diffuse reflectance spectroscopy (DRS) to provide information about the biochemical composition of living tissue. During DRS measurements, the incident, visible light is partially absorbed by chromophores but also scattered in the tissue before being remitted. LÄS MER
