  1. 1. Optical Methods for Tympanic Membrane Characterisation Towards Objective Otoscopy in Otitis Media

    University dissertation from Institutionen för medicinsk teknik

    Author : Mikael Sundberg; Tomas Strömberg; Ton van Leeuwen; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical Methods; Spectroscopy; Surface Curvature; Monte Carlo; Tympanic Membrane; Otitis Media; TECHNOLOGY Other technology Medical engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Medicinsk teknik;

    Abstract : 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.

  2. 2. Optical Characterisation of Miniature Structures and Translucent Sheets for Daylighting Applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jacob Jonsson; Arne Roos; Helen Rose-Wilson; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Photospectrometry; Light scattering; Optical characterisation; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : For a long time spectrophotometry has been a powerful method of determining optical material properties. Since the technique measures the parameters of interest, reflectance and transmittance, it is in general easy to use and interpret. READ MORE
